Most SD controllers need some kind of alignment for writing
blocks. Instead of coding this in every driver, align write
blocks to a 4 byte alignment in the mci layer. For DMA
accesses we may need bigger alignment, but let's solve this
problem when we have it.

With SD cards older than 2.0 the sd_send_if_cond() fails. Do
not assume it's an MMC card in this case. Instead, assume
it's a MMC card if sd_send_op_cond() fails.

This adds the basic framework to handle MCI cards in barebox.
