Allow FIS cmd to handle multiple flash devices with different block alignments

This patch allows Redboot FIS command to manage multiple flash devices even
when the flash devices have different block sizes/alignments.

Note this is not about different block sizes in a single flash device, this is
about different block sizes in multiple flash devices.

Noticed this problem with Redboot on a board that has embedded flash in SoC and
also a SPI dataflash device. Most FIS operations were failing because it was
using alignment from embedded flash even on dataflash device.
