[PATCH v2 5/6] MIPS: perf: Fold vpe_id() macro into it's one last usage

[Matt Redfearn <matt.redfearn@mips.com>]

The vpe_id() macro is now used only in mipsxx_pmu_enable_event when
CONFIG_CPU_BMIPS5000 is defined. Fold the one used definition of the
macro into it's usage and remove the now unused definitions.

Since we know that cpu_has_mipsmt_pertccounters == 0 on BMIPS5000,
remove the test on it and just set the counter to count the relevant
VPE.

Changes in v2:
Since BMIPS5000 does not implement per TC counters, we can remove the
check on cpu_has_mipsmt_pertccounters.
