perf dwarf-regs: Move csky dwarf-regs out of arch

Move arch/csky/util/dwarf-regs.c to util/dwarf-regs-csky.c and compile
in unconditionally. To avoid get_arch_regstr being duplicated, rename
to get_csky_regstr and add to get_dwarf_regstr switch.

Update #ifdefs to allow ABI V1 and V2 tables at the same
time. Determine the table from the ELF flags.
