MIPS: Add crc instruction support flag to elf_hwcap

Browse Source 
Indicate that CRC32 and CRC32C instuctions are supported by the CPU
through elf_hwcap flags.

This will be used by a follow-up commit that introduces crc32(c) crypto
acceleration modules and is required by GENERIC_CPU_AUTOPROBE feature.
