[PATCH v2 0/3] arm64: cpufeature: constify and refactor feature array

This is v2 of the series that constifies and refactors the cpufeatures data
structures, in a way that allows certain pieces to be referenced directly by
external code. This was triggered by the discussion around Suzuki's CTR
emulation series [0]

Changes since v1/RFC:
- replace 'if (<cond>) { BUG(); }' with 'BUG_ON(<cond>);' (#2)
- don't dereference NULL return value of bsearch() (#2)
- rename global ctrel0_ftr_reg to arm64_ftr_reg_ctrel0 (#3)
- add Suzuki's R-b (#1, #2, #3)
