fw_base.S: Fix assembler error with clang 16+
Attempting to build OpenSBI with clang 16 and the following command:
$ make LLVM=1 PLATFORM=generic
Results in the following error:
AS platform/generic/firmware/fw_dynamic.o
/tmp/fw_dynamic-d000a6.s:429:9: error: symbol '_fw_start' can not be undefined in a subtraction expression
.dword _fw_rw_start - _fw_start
Work around this issue by eliminating the __fw_rw_offset variable and
performing the offset calculation at run-time instead. This takes
advantage of the fact that the a4 register contains the value of
_fw_start.
