ARM: 7357/1: perf: fix overflow handling for xscale2 PMUs
commit 3f31ae121348afd9ed39700ea2a63c17cd7eeed1 upstream.
xscale2 PMUs indicate overflow not via the PMU control register, but by
a separate overflow FLAG register instead.
This patch fixes the xscale2 PMU code to use this register to detect
to overflow and ensures that we clear any pending overflow when
disabling a counter.
