Enable the use of SDMA mode to boost eMMC performance on ROCK Pi 4. Also add missing flags to indicate the supported MMC modes.
Using mmc read command to read 32 MiB data shows following improvement:
=> time mmc read 10000000 2000 10000
Before: time: 3.178 seconds After: time: 0.402 seconds
This also enables CONFIG_SPL_FIT_SIGNATURE option to help discover any possible future issue with loading TF-A into DRAM/SRAM.
