arm64: capabilities: Move errata processing code

Browse Source 
We have errata work around processing code in cpu_errata.c,
which calls back into helpers defined in cpufeature.c. Now
that we are going to make the handling of capabilities
generic, by adding the information to each capability,
move the errata work around specific processing code.
No functional changes.
