Revert "arm64: errata: Workaround possible Cortex-A715 [ESR|FAR]_ELx corruption"
This reverts commit 44ecda71fd8a70185c270f5914ac563827fe1d4c. All versions of this patch on the mailing list, including the version that ended up getting merged, have portions of code guarded by the non-existent CONFIG_ARM64_WORKAROUND_2645198 option. Although Anshuman says he tested the code with some additional debug changes [1], I'm hesitant to fix the CONFIG option and light up a bunch of code right before I (and others) disappear for the end of year holidays, during which time we won't be around to deal with any fallout. So revert the change for now. We can bring back a fixed, tested version for a later -rc when folks are thinking about things other than trees and turkeys.
