Fix SMCCC_ARCH_SOC_ID implementation

Commit 0e753437e75b ("Implement SMCCC_ARCH_SOC_ID SMC call") executes
and return the result of SMCCC_ARCH_SOC_ID(soc_id_type) to the
SMCCC_ARCH_FEATURES(SMCCC_ARCH_SOC_ID) itself. Moreover it expect to
pass soc_id_type for SMCCC_ARCH_FEATURES(SMCCC_ARCH_SOC_ID) which is
incorrect.

Fix the implementation by returning SMC_OK for
SMCCC_ARCH_FEATURES(SMCCC_ARCH_SOC_ID) always and move the current
implementation under "smccc_arch_id" function which gets called from
SMC handler on receiving "SMCCC_ARCH_SOC_ID" command.

This change is tested over linux operating system
