aarch64: Update feature RAS system registers
This patch: + updates RAS feature system registers with new RAS 1.1 regs. + extends RAS/RAS 1.1 support for all architecture levels of Armv8-A. Please note that early Armv8-A architectures do not officially support RAS extension. Rationale of the patch: To ease development so that user-friendly RAS system registers operands can be used. Certain use cases require developers to enable only more generic architecture (e.g. -march=armv8-a) during system development. Users must use RAS extension registers bearing in mind that system they use must support it. The RAS (Reliability, Availability, Serviceability) extension is a system-level extension that defines a number of system registers. RAS 1.1 (FEAT_RASv1p1) introduces five new system registers: ERXPFGCTL_EL1, ERXPFGCDN_EL1, ERXMISC2_EL1, ERXMISC3_EL1 and ERXPFGF_EL1. For details see [0].
