drm: vkms: Add support to the RGB565 format
This commit also adds new helper macros to deal with fixed-point
arithmetic.
It was done to improve the precision of the conversion to ARGB16161616
since the "conversion ratio" is not an integer.
V3: Adapt the handlers to the new format introduced in patch 7 V3.
V5: Minor improvements
V6: Minor improvements (Pekka Paalanen)
