Pull allocation from first_init to a new function in hda_controller.c.
Short term this will allow the dsp loader to be moved as well.  In
later commits it will allow the same allocation to be used by the
platform hda driver.

Pull the pcm_ops and the functions they use into a new hda_controller
file.  This is done to allow for other hda implementations besides PCI
to use the same ops.  The hda_controller file will house functionality
related to HDA but independent of the bus used to talk to the
controller.

This currently shares dsp locking across the two files.  This will be
remedied in a following commit.

Break out the allocation of pages for DMA and PCM buffers to ops in
the chip structure.  This is done to allow for architecture specific
work-arounds to be added.  Currently mark_pages_wc is used by
hda_intel.  This avoids needing to move that x86-specific code to a
common area shared with hda platform drivers.

Passing the max slots and power save arguments to codec_create will
allow for its reuse by an hda_platform driver. It makes the function
independent of the module params in hda_intel and ready to move to
hda_shared in a following commit.

Keeping a pointer to the jackpoll_ms array in the chip will allow
azx_codec_create to be shared between hda_intel and hda_platform
drivers.  Also modify get_jackpoll_ms to make the jackpoll_ms member
optional, this way a platform driver can leave it out if it's not
needed.

This is a PCI-only feature, but adding a callback for it in the chip

The forthcoming platform hda driver needs to override the way
registers are read and written.  In preparation for that, introduce a
reg_ops struct that can be implemented differently by the new driver.
Change the existing macros to use the new structure, and move them to
hda_priv.h where they will be accessible to both PCI and platform
drivers.

Start with register access, but later commits will add more ops that
differ between PCI and platform.

Later commits adding support for hda platform drivers will want to use

hda_intel and the new platform driver.

According to the HDA spec, we must write 1 to bit 15 on a CORBRP
reset, read back 1, then write 0, then read back 0. This must be
done while the DMA is not running.

We accidentaly ended up writing back the 0 by using a writel
instead of a writew to CORBWP.

This caused occasional controller failure on Bay Trail hardware.

The beep input device is registered via input_register_device(), but
this is called in snd_hda_attach_beep_device() where the sound devices
aren't registered yet.  This leads to the binding to non-existing
object, thus results in failure.  And, even if the binding worked
(against the PCI object), it's still racy; the input device appears
before the sound objects.

For fixing this, register the input device properly at dev_register
ops of the codec object it's bound with.  Also, call
snd_hda_detach_beep_device() at dev_disconnection so that it's
detached at the right timing.  As a bonus, since it's called in the
codec's ops, we can get rid of the further call from the other codec
drivers.

This merges the bunch of changes over pci and usb sound drivers to
convert to dev_err() and co.

Many HP laptops with STAC codecs have a docking station port and BIOS
sets the pins for the input on the dock as a line in.  Because the
generic parser doesn't handle a line in pin as auto-switchable, this
resulted in the manual capture source selection on these laptops.

However, from the usability POV, the automatic switching is easier.
This patch adds the line_in_auto_switch hint in the fixup function for
these laptops.  Even if no dock port is present, this should be
harmless as the generic parser allows the auto-switching only in a
limited situation (all three pins are located in different
positions).
