perf parse-regs: Always build perf register functions

Currently, the macro HAVE_PERF_REGS_SUPPORT is used as a switch to turn
on or turn off the code of perf registers. If any architecture cannot
support perf register, it disables the perf register parsing, for both
the native parsing and cross parsing for other architectures.

To support both the native parsing and cross parsing, the tool should
always build the perf regs functions. Thus, this patch removes
HAVE_PERF_REGS_SUPPORT from the perf regs files.
