Sowjanya Komatineni 4c4faff62b mmc: sdhci: Add ADMA3 DMA support for V4 enabled host
Below are the supported DMA types in Host Control1 Register
with Version 4 enable
b'00 - SDMA
b'01 - Not Used
b'10 - ADMA2
b'11 - ADMA2 or ADMA3

ADMA3 uses Command Descriptor to issue an SD command.
A multi-block data transfer is performed by using a pair of CMD
descriptor and ADMA2 descriptor.

ADMA3 performs multiple of multi-block data transfer by using
Integrated Descriptor which is more suitable for Command Queuing
to fetch both Command and Transfer descriptors.

Host Capabilities register indicates the supports of ADMA3 DMA.
