MIPS: Fix ISA I/II FP signal context offsets
Fix a regression introduced with commit 2db9ca0a3551 ("MIPS: Use struct mips_abi offsets to save FP context") for MIPS I/I FP signal contexts, by converting save/restore code to the updated internal API. Start FGR offsets from 0 rather than SC_FPREGS from $a0 and use $a1 rather than the offset of SC_FPC_CSR from $a0 for the Floating Point Control/Status Register (FCSR). Document the new internal API and adjust assembly code formatting for consistency. Signed-off-by: Maciej W.
