Bipin Ravi 9b2510b69d fix(security): apply SMCCC_ARCH_WORKAROUND_3 to A73/A75/A72/A57 ... This patch applies CVE-2022-23960 workarounds for Cortex-A75, Cortex-A73, Cortex-A72 & Cortex-A57. This patch also implements the new SMCCC_ARCH_WORKAROUND_3 and enables necessary discovery hooks for Coxtex-A72, Cortex-A57, Cortex-A73 and Cortex-A75 to enable discovery of this SMC via SMC_FEATURES. SMCCC_ARCH_WORKAROUND_3 is implemented for A57/A72 because some revisions are affected by both CVE-2022-23960 and CVE-2017-5715 and this allows callers to replace SMCCC_ARCH_WORKAROUND_1 calls with SMCCC_ARCH_WORKAROUND_3. For details of SMCCC_ARCH_WORKAROUND_3, please refer SMCCCv1.4 specification.
