The following macros were introduced in power7-pmu via
commit 4da52960fd1a ("perf_counters: powerpc: Add
support for POWER7 processors")

PM_PMC_MSKS, PM_COMBINE_MSKS, MMCR1_TTM1SEL_SH,
MMCR1_TTM2SEL_SH, MMCR1_TTM3SEL_SH, MMCR1_TTMSEL_MSK,
MMCR1_L2SEL_MSK, MMCR1_PMC2_COMBINE_SH, MMCR1_PMC3_COMBINE_SH,
MMCR1_PMC4_COMBINE_SH, MMCR1_PMC2SEL_SH, MMCR1_PMC3SEL_SH,
MMCR1_PMC4SEL_SH, MMCR1_PMCSEL_MSK

Removing the above macros as they are defined but never used.
