[PATCH v2 08/17] arm64/sysreg: Make BHB clear feature defines match the architecture

[Mark Brown]

The architecture refers to the field identifying support for BHB clear as
BC but the kernel has called it CLEARBHB. In preparation for generation of
defines for ID_AA64ISAR2_EL1 rename to use the architecture's naming. No
functional changes.
