Nicholas Piggin 9c9767504d lib: sbi: Drop fw_rw_offset alignment requirement for single fw region ...

In a single fw region scheme, there is no separate PMP created for RW
memory. The checks that opensbi does for the alignment between fw_start
and fw_rw_start (using fw_rw_offset) and the power of 2 check for
fw_rw_offset are no longer necessary.

Update sbi_domain_init so that these checks are only done in the non
single fw region scheme.
