soc/software/litesdcard: update for response register back to 128 bits

The additional (17th) byte returned via the response register was
ignored by software (bios and kernel), so LiteSDCard was updated
to only return the (original, useful) 128 bits.

This patch updates the LiteSDCard code in the LiteX bios to only
expect those 128 bits, and to do so in a manner that's portable
across CSR data widths and alignments.
