- OMAP ATAG changes:
        FBMEM - support for per plane memory configurations
        LCD   -  add data_lines, reset GPIO line params

- FB memory configuration:
        Support for per-plane memory configurations with FB location
        either in SRAM or SDRAM.

- DMA consistent memory size:
        Make the ARM DMA consistent memory size overridable. The default
        is 2MB, but for larger frame buffers we may need more. Kconfig
        option is added in the next patch.
