[PATCH v3 03/15] lib: sbi: Add Xandespmu in hart extensions

[Yu Chien Peter Lin]

When SBI PMU updates inhibit bits on mcyclecfg and
minstretcfg, it will check if Smcntrpmf extension
is supported, we need to check Xandespmu similarly
in the pmu_fixed_ctr_update_inhibit_bits() so add
the custom extension to hart extension list.
