Add grok/write functions for new ppc core note sections

This patch adds functions for grokking and writing more register core
note sections (NT_PPC_TAR, NT_PPC_PPR, NT_PPC_DSCR, NT_PPC_EBB,
NT_PPC_PMU, NT_PPC_TM_CGPR, NT_PPC_TM_CFPR, NT_PPC_TM_CVMX,
NT_PPC_TM_CVSX, NT_PPC_TM_SPR, NT_PPC_TM_CTAR, NT_PPC_TM_CPPR,
NT_PPC_TM_CDSCR).
