LoongArch: Fix probing of the CRC32 feature
commit df830336045db1246d3245d3737fee9939c5f731 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.
