perf: pmuv3: Change GENMASK to GENMASK_ULL
GENMASK macro uses "unsigned long" (32-bit wide on arm and 64-bit
on arm64), This causes build issues when enabling PMUv3 on arm as
it tries to access bits > 31. This patch switches the GENMASK to
GENMASK_ULL, which uses "unsigned long long" (64-bit on both arm
and arm64).
