Log:
  MFC r306557, r307240, r307241:
  
  r306557:
  Use VM_MEMATTR_WRITE_COMBINING memattr for mmap(2) on framebuffer
  
  VM_MEMATTR_WRITE_COMBINING sets write-through cache flag for framebuffer
  memory that prevents pixel data from being stuck in cache until evicition
  happens
  
  r307240:
  Fix BCM238x framebuffer driver build for ARM64
  
  VM_MEMATTR_WRITE_COMBINING can be undefined for some platforms, use it only
  if it's defined
  
  r307241:
  Do not set FB_FLAG_MEMATTR if VM_MEMATTR_WRITE_COMBINING is not available
