fmap: Avoid unaligned access

The fmap header has unaligned fields in it. Some CPUs do not like this,
and it is not very friendly to hide this sort of thing in innocuous code.

Fix it by copying the data into an aligned location first only for
vboot_before_bootblock. Because verstage runs as a userspace
application, we can't set up caching as would be the typical way
to handle this.

BUG=b:153203967
TEST=See this output now in psp_verstage
Getting SPI ROM info.
FMAP: base = 0xff000000 size = 0x1000000 #areas = 29
