Exists in master and in 7 other branches imx_3.0.35_4.1.0, imx_3.10.17_1.0.1_ga, imx_3.10.53_1.1.0_ga, imx_3.14.28_1.0.0_ga, smarc-imx_3.10.53_1.1.0_ga, smarc-imx_3.14.28_1.0.0_ga, smarc-l5.0.0_1.0.0-ga

powerpc: Update compat_arch_ptrace 

Update compat_arch_ptrace to follow recent changes in
PTRACE_GET_DEBUGREG and the addition of
PPC_PTRACE_{GETHWDBGINFO|{SET|DEL}HWDEBUG}.  The latter three can be
forwarded to arch_ptrace unchanged.
