Register physical addresses are remapped and the register mmio
addresses for lcd,mipi and msscam are saved in drm_private.
All register reads/writes are updated to get the mmio offset
from this structure. We are using hardcoded values for register
physical addresses and this will be modified to read from device
tree in the future.
v2: minor code review changes
v3: upclassed dev_private
