FMC2 IP supports up to 4 chip select. On MP1 SoC, only 2 of them are
available when on MP25 SoC, the 4 chip select are available.

For MP1 SoCs, MDMA is used and the max burst size is 128.
For MP25 SoC, DMA3 is used and the max burst size is 64.

Changes in v2:
 - dt-bindings commit message has been updated.
 - V1 patch 10, 11 and 12 have been squashed and reworked.
