Perf: Restore correct CPU's PMU counters after power collpase

Since the L1CC PMU's are per CPU, the variable to detect if a CPU
came out of powercollapse also needs to be a per CPU variable. This
ensures that we reset and restore the correct CPU's PMU counters.

Perf: Make L1 PMU IRQ name target independent

Remove target name from IRQ string, since the percpu IRQ API
is shared with all Qcomm targets.

Perf: Change IRQ functions for CPU variants

Unicore targets can't use the percpu IRQ API,
so fallback to the generic versions of the functions
at init.

Perf: Add generic IRQ handlers for ARMv7 PMU's

For ARMV7 based PMU's implemented outside Qcomm, default
to the generic IRQ handlers to maintain original behavior.

Perf: Let platforms decide IRQ request methods.

This is in preparation for adding support for the unicore A5
and dualcore A5, both of which have the same MIDR value.

Instead of adding extra parsing to the ARM generic perf_event file,
this patch moves it to the 'mach' directory where targets types
can be detected in an implementation specific manner.

The default behavior is maintained for all other ARM targets.

msm: perf: Relax Column exclusion checks for L2CC events

Identical L2CC events with the same register, code and group

restricts counting only for identical register and group settings
but a different value for the event code.

Detect such identical events and let them pass the constraint
checks.

Perf: Toggle PMU IRQ when CPU's are hotplugged

When a CPU is hotplugged out while a perf session
is active, disarm the IRQ when the CPU is preparing
to die. This ensures that perf doesn't lock up when
it tries to free the irq of a hotplugged CPU.
Similarly, when a CPU comes online during a perf session
enable the IRQ so that perf doesn't try to disable
an unarmed IRQ when it finishes.
