perf: starfive: fix 64-bit only COMPILE_TEST condition (2024-03-19 19:01:39 +0000)

----------------------------------------------------------------
arm64 fix/update:

- Re-instate the CPUMASK_OFFSTACK option for arm64 when NR_CPUS > 256. The bug that led to the initial revert was the cpufreq-dt code not using zalloc_cpumask_var().

- Make the STARFIVE_STARLINK_PMU config option depend on 64BIT to prevent compile-test failures on 32-bit architectures due to missing writeq().
