Arvind Ram Prakash 8ae6b1ad6c fix(security): apply SMCCC_ARCH_WORKAROUND_4 to affected cpus ... This patch implements SMCCC_ARCH_WORKAROUND_4 and allows discovery through SMCCC_ARCH_FEATURES. This mechanism is enabled if CVE_2024_7881 [1] is enabled by the platform. If CVE_2024_7881 mitigation is implemented, the discovery call returns 0, if not -1 (SMC_ARCH_CALL_NOT_SUPPORTED). For more information about SMCCC_ARCH_WORKAROUND_4 [2], please refer to the SMCCC Specification reference provided below.
