LoongArch: Fix probing of the CRC32 feature
commit df83033 upstream. Not all LoongArch processors support CRC32 instructions. This feature is indicated by CPUCFG1.CRC32 (Bit25) but it is wrongly defined in the previous versions of the ISA manual (and so does in loongarch.h). The CRC32 feature is set unconditionally now, so fix it. BTW, expose the CRC32 feature in /proc/cpuinfo.
