firmware: Fix fw_rw_offset computation in fw_base.S
It seems BFD just does totally nonsensical things for SHN_ABS symbols
when producing position-independent outputs (both -pie and -shared)
for various historical reasons, and so SHN_ABS symbols are still
subject to relocation as far as BFD is concerned (except AArch64,
which fixes it in limited cases that don’t apply here...).
The above affects the _fw_rw_offset provided through fw_base.ldS
linker script which results in OpenSBI firmware failing to boot
when loaded at an address different from FW_TEXT_START.
Fixes: c10e3fe5f9a1 ("firmware: Add RW section offset in scratch")
