Fix NULL-dereference introduced by OMAP4 PMU patch
This patch fixes a NULL-dereference introduced by commit 457520e ("arm: pmu: support pmu/perf on OMAP4"). Some platforms (e.g. vexpress) neither need nor have an instance of arm_pmu_platdata (plat). Perf support on these platforms was broken by the original commit. This patch adds a check for plat before dereferencing any fields.
