drm/pl111: Support variants with broken VBLANK
The early Integrator CLCD synthesized in the Integrator CP and
IM-PD1 FPGAs are broken: their vertical and next base interrupts
are not functional. Support these variants by simply disabling
the use of the vblank interrupt on these variants.

drm/pl111: Support variants with broken clock divider
The early Integrator CLCD synthesized in the Integrator CP and
IM-PD1 FPGAs are broken: their clock dividers do not work
properly. Support disabling the clock divider and drive the
clock directly from the parent under these circumstances.

drm/pl111: Properly detect the ARM PL110 variants
With a bit of refactoring we can contain the variant data for
the strange PL110 versions that is feature-incomplete PL110 for
the ARM Integrator/CP and somewhere inbetween PL110 and PL111
for the ARM Versatile AB and Versatile PB.
We also accomodate for the custom duct-taped RGB565/BGR565 support
in the Versatile variant.

drm/pl111: Add handling of Versatile platforms
The ARM reference designs in the Versatile family: Integrator,
Versatile and RealView can make use of the new DRM driver as well.
We just need to create a bit of platform-specific code for them
that we isolate to its own file.
