mmc: sdhci: Parameterize ADMA sizes and alignment
In preparation for 64-bit ADMA, parameterize ADMA sizes
and alignment. 64-bit ADMA has a larger descriptor
because it contains a 64-bit address instead of a 32-bit
address. Also data must be 8-byte aligned instead
of 4-byte aligned. Consequently, sdhci_host members
are added for descriptor, table, and buffer sizes
and alignment.
