At least since the atomic port, the vmwgfx fbdev code is taking
a number of unnecessary modeset locks. In particular the
kms_set_config() function will grab its own locks, leading to
locking retries. So avoid drm_modeset_lock_all() and instead
provide a local acquire context for kms_set_config(). Also have the
vmw_kms_fbdev_init data itself grab the lock that it needs.

This also fixed a long standing problem that vmw_fb_close() didn't
provide an acquire context for kms_set_config(), causing potential
warnings and hangs during driver unload. This problem was uncovered by the
recent commit "drm/vmwgfx: Improve on hibernation"

Testing done:
Repeated driver load and unload on Ubuntu 16.04.2

We're currently failing to reset everything in display_info.hdmi
which will potentially cause us to use stale information when
swapping monitors. Eg. if the user replaces a HDMI 2.0 monitor
with a HDMI 1.x monitor we will continue to think that the monitor
supports scrambling. That will lead to a black screen since the
HDMI 1.x monitor won't understand the scrambled signal.

Fix the problem by clearing display_info.hdmi fully. And while at
eliminate some duplicated code by calling drm_reset_display_info()
in drm_add_display_info().

The reverted commit broke LVDS output on TBS A711 Tablet. That tablet
has simple-panel node that has fixed pixel clock-frequency that A83T
SoC used in the tablet can't generate exactly.

Requested rate is 52000000 and rounded_rate is calculated as 51857142.
It's close enough for it to work in practice, but with strict check
in the reverted commit, the mode is rejected needlessly in this case.

DT allows to specify a range of values for simple-panel/clock-frequency,
but driver doesn't respect that ATM. Given that TBS A711 is the single
user of sun4i-lvds driver, let's revert that commit for now, until
a better solution for the problem is found.

Also see: https://patchwork.kernel.org/patch/9446385/ for relevant
discussion (or search for "[RFC] drm/sun4i: rgb: Add 5% tolerance

The below commit

    "drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2"

introduces a slight behavioral change to rmfb. Instead of disabling a crtc
when the primary plane is disabled, it now preserves it.

Since DC is currently not equipped to handle this we need to fail such
a commit, otherwise we might see a corrupted screen.

This is based on Shirish's previous approach but avoids adding all
planes to the new atomic state which leads to a full update in DC for
any commit, and is not what we intend.

Theoretically DM should be able to deal with states with fully populated planes,
even for simple updates, such as cursor updates. This should still be
addressed in the future.

Pull libnvdimm fixes from Dan Williams:
 "A regression fix, new unit test infrastructure and a build fix:

   - Regression fix addressing support for the new NVDIMM label storage
     area access commands (_LSI, _LSR, and _LSW).

     The Intel specific version of these commands communicated the
     "Device Locked" status on the label-storage-information command.

     However, these new commands (standardized in ACPI 6.2) communicate
     the "Device Locked" status on the label-storage-read command, and
     the driver was missing the indication.

     Reading from locked persistent memory is similar to reading
     unmapped PCI memory space, returns all 1's.

   - Unit test infrastructure is added to regression test the "Device
     Locked" detection failure.

   - A build fix is included to allow the "of_pmem" driver to be built
     as a module and translate an Open Firmware described device to its
     local numa node"
