perf tools: Copy uapi/asm/perf_regs.h from the kernel for MIPS
To allow the build to complete on older systems, where those files are either not uptodate, lacking some recent additions or not present at all. And check if the copy drifts from the kernel. This commit is similar with commit 12f020338a2c ("tools: Copy uapi/asm/perf_regs.h from the kernel") With this commit, we can avoid the following build error in any case: tools/perf/arch/mips/include/perf_regs.h:7:10: fatal error: asm/perf_regs.h: No such file or directory #include <asm/perf_regs.h> ^~~~~~~~~~~~~~~~~ compilation terminated.
