Use hwmon_device_register_with_groups instead of deprecated
hwmon_device_register and fix a dmesg warning.

This patch however changes the userspace API.
hwmon_device_register_with_groups takes `hwmon' name as an argument and
creates a name file in the `hwmon' device, not in the `platform_device'.
This allows us to remove custom `name' device attribute, but in order to
make lm-sensors happy we also have to move fans and thermal attributes
to the `hwmon' device.

Even though this patch changes userspace API, it's still compatible with
the lm-sensors. Starting with lm-sensors 3.0 (circa 2007), it looks at
both hwmon and the backing device for the name and other attributes.

Although this driver did pretty good job in abstracting PCH specific
interfaces, but still there are some loose ends. For example
SLP_S0 counter (for reading SLP_S0 residency), PM config offset (for
checking permissions to read XRAM) and PPFEAR offset (for reading IP
status) is still hardcoded for a specific family of PCH.

This change extended the struct pmc_reg_map to allow per family
configuration of offsets and bits.

No functional change is expected with this change. This change allows
seamless additions to new PCH and create a baseline for other platform
specific extensions.

The WMI queries are performed by evaluating the WMPV() method from ACPI
DSDT tables, and it takes three arguments: instance index, method id and
input data (buffer).

Currently the method id is hard-coded to 0x3 in hp_wmi_perform_query()
which means that it will perform WMI calls that expect an output data of
size 0x80 (128). The output size is usually OK for the WMI queries we
perform, however it would be better to pick the correct one before
evaluating the WMI method.

Which correct method id to choose can be figured out by looking at the
following ASL code from WVPI() method:

...
Name (PVSZ, Package (0x05)
            {
            Zero,
            0x04,
            0x80,
            0x0400,
            0x1000
            })
Store (Zero, Local0)
If (LAnd (LGreaterEqual (Arg1, One), LLessEqual (Arg1, 0x05)))
{
    Store (DerefOf (Index (PVSZ, Subtract (Arg1, One))), Local0)
}
...

Arg1 is the method id and PVSZ is the package used to index the
corresponding output size; 1 -> 0, 2 -> 4, 3 -> 128, 4 -> 1024, 5 ->
4096.

This patch maps the output size passed in hp_wmi_perform_query() to the
correct method id before evaluating the WMI method.

This fixes a problem where the system gets stuck in a loop
unable to wakeup via power button in s2idle.

The problem happens because:
 - press power button:
   - system emits 0xc0 (power press), event ignored
   - system emits 0xc1 (power release), event processed,
     emited as KEY_POWER
   - set wakeup_mode to true
   - system goes to s2idle
 - press power button
   - system emits 0xc0 (power press), wakeup_mode is true,
     system wakes
   - system emits 0xc1 (power release), event processed,
     emited as KEY_POWER
   - system goes to s2idle again

To avoid this situation, process the presses (which matches what
intel-hid does too).

When I converted dell-wmi to the new bus infrastructure, I left the
call to dell_wmi_check_descriptor_buffer() in dell_wmi_init().  This
could cause two problems:

 - An error message when loading the driver on a system without
   dell-wmi.  We'd try to read the event descriptor even if the WMI
   GUID wasn't there.

 - A possible race if dell-wmi was loaded manually before wmi was
   fully initialized.

Fix it by moving the call to the probe function where it belongs.

drivers/platform/x86/alienware-wmi.c:461:3: note: 'sprintf' output between 7 and 13 bytes into a destination of size 10

This replaces the 'int' variable with an 'u8' to make sure
it always fits, renaming the variable to 'zone' for clarity.

Unfortunately, gcc-7.1.1 still warns about it with that change, which
seems to be unintended by the gcc developers. I have opened a bug
against gcc with a reduced test case. As a workaround, I also
change the format string to use "%02hhX", which shuts up the
warning in that version.

Unfortunately, on some models of some architectures getting a fully
seeded CRNG is extremely difficult, and so this can result in dmesg
getting spammed for a surprisingly long time.  This is really bad from
a security perspective, and so architecture maintainers really need to
do what they can to get the CRNG seeded sooner after the system is
booted.  However, users can't do anything actionble to address this,
and spamming the kernel messages log will only just annoy people.

For developers who want to work on improving this situation,
CONFIG_WARN_UNSEEDED_RANDOM has been renamed to
CONFIG_WARN_ALL_UNSEEDED_RANDOM.  By default the kernel will always
print the first use of unseeded randomness.  This way, hopefully the
security obsessed will be happy that there is _some_ indication when
the kernel boots there may be a potential issue with that architecture
or subarchitecture.  To see all uses of unseeded randomness,
developers can enable CONFIG_WARN_ALL_UNSEEDED_RANDOM.
