binutils: backport patch to fix mipsel (malta) kernel compile

This fixes the following compilation error when building a mipsel
yocto kernel for qemu:

|   CC      arch/mips/mm/sc-ip22.o
| {standard input}: Assembler messages:
| {standard input}:128: Error: number (0x9000000080000000) larger than 32 bits
| {standard input}:151: Error: number (0x9000000080000000) larger than 32 bits
| {standard input}:186: Error: number (0x9000000080000000) larger than 32 bits

We leave out the testsuite bits and the changelog in this
backport.

+Subject: [PATCH] MIPS/GAS: Fix an ISA override not lifting ABI restrictions
+
+Correct a regression introduced with commit 919731affbef ("Add MIPS
+.module directive") causing code like:
+
+	.set	mips3
+	dli	$2, 0x9000000080000000
+
+to fail assembly with the following error message produced:
+
+Error: number (0x9000000080000000) larger than 32 bits
+
+if built with `mips3' selected as the global ISA (e.g. `-march=mips3').
+This is because a `.set' directive doing an ISA override does not lift
+the ABI restriction on register sizes if the ISA remains unchanged.
+Previously the directive always set register sizes from the ISA chosen,
+which is what some code expects.  Restore the old semantics then.
+
+	gas/
+	* config/tc-mips.c (code_option_type): New enum.
+	(parse_code_option): Return status indicating option type.
+	(s_mipsset): Update `parse_code_option' call site accordingly.
+	Always set register sizes from the ISA with ISA overrides.
+	(s_module): Update `parse_code_option' call site.
