arm/raspberrypi: framebuffer driver checks for initialization and tries runtime init if required.
Code works but there is problem how to setup caching for the regions
(arm_cp15_set_translation_table_entries arguments).
If ARMV7_MMU_DATA_READ_WRITE_CACHED is used then CPU
accesses are noncoherent with VideoCore and some
part of image update are not visible until pushed from
cache by other activities. If ARMV7_MMU_DATA_READ_WRITE
is used then access is extremely slow.
