flash_map: Increase minimum supported write align via
flash_area_align
MCUboot changed the type of the alignment value in flash from a uint8_t
to a uint32_t. Indeed, Zephyr contains flash devices that have a larger
alignment than will fit in an 8-bit value. This generally means that
`flash_area_align` will just return 0 on these platforms.
Change call in Zephyr as well.
This shouldn't cause any observable behavior changes in Zephyr, other
than making some cases that don't work currently begin to work. If a
client is storing these results in a u8, it will be truncated, the same
as things were previously. If, however, the caller is prepared to
handle a larger type, this will result in having correct information,
instead of the truncated value.
