fbdev: da8xx/omap-l1xx: implement double buffering
This work includes the following:
- Implement handler for FBIO_WAITFORVSYNC ioctl.
- Allocate the data and palette buffers separately. A consequence of
this is that the palette and data loading is now done in different
phases. And that the LCD must be disabled temporarily after the palette
is loaded but this will only happen once after init and each time the
palette is changed. I think this is OK.
- Allocate two (ping and pong) framebuffers from memory.
- Add pan_display handler which toggles the LCDC DMA registers between
the ping and pong buffers.
