LVDS panel, make/model described as:

AU Optronics Corporation - B101XTN01.0 (H/W:0A)

LVDS panel support uses the LCDC (parallel) encoder.  Unlike with HDMI,
there is not a separate LVDS block, so no need to split things into a
bridge+connector.  Nor is there is anything re-used with mdp5.

Note that there can be some regulators shared between HDMI and LVDS (in
particular, on apq8064, ext_3v3p), so we should not use the _exclusive()
variants of devm_regulator_get().

The drm_panel framework is used for panel-specific driver.

In particular, blend_setup() should not overwrite the other crtc's mixer
settings.  Also, the encoder needs to be able to specify the mixer-id
explicitly, since both LVDS and DTV use 'INTF_LVDC_DTV', so we cannot
guess the mixer-id from the interface.

One step closer to dropping all the drm_bus_* code:
Add a driver->set_busid() callback and make all drivers use the generic
helpers. Nouveau is the only driver that uses two different bus-types with
the same drm_driver. This is totally broken if both buses are available on
the same machine (unlikely, but lets be safe). Therefore, we create two
different drivers for each platform during module_init() and set the
set_busid() callback respectively.

DRM_DEBUG_CODE is currently always set, so distributions enable it. The
only reason to keep support in code is if developers wanted to disable
debug support. Sounds unlikely.

All the DRM_DEBUG() printks are still guarded by a drm_debug read. So if
its cacheline is read once, they're discarded pretty fast.. There should
hardly be any performance penalty, it's even guarded by unlikely().

It is hardly possible to review the drmP.h includes, anymore. Order them
alphabetically, linux/ first, then asm/ and then local drm/ includes.

Since a long time ago, kernel headers have been converted to include
required headers themselves. No-one cares whether that means the compiler
has to include a header multiple times. In fact, GCC already does some
optimization regarding multiple inclusions if a sorrounding #ifndef is
present.

pte_wrprotect() is only used by drm_vm.c, so move the include there. Also
include it unconditionally, all architectures provide this header!

Furthermore, replace asm/current.h with sched.h, which includes
asm/current.h unconditionally. This way we get the same effect and avoid
direct asm/ includes. Furthermore, drop the weird __alpha__ protection.
It's safe to include sched.h everywhere (and the wait.h comment doesn't
