powerpc/perf: Fix MMCRA_BHRB_DISABLE define for binutils < 2.28

Commit 9908c826d5ed ("powerpc/perf: Add Power10 PMU feature to DT CPU
features") defines MMCRA_BHRB_DISABLE as `0x2000000000UL`. Binutils
version less than 2.28 doesn't support UL suffix.

Fix this by wrapping it with the `_UL` macro.
