arm64: spectre: Rename spectre_v4_patch_fw_mitigation_conduit
The spectre-v4 sequence includes an SMC from the assembly entry code.
spectre_v4_patch_fw_mitigation_conduit is the patching callback that
generates an HVC or SMC depending on the SMCCC conduit type.
As this isn't specific to spectre-v4, rename it
smccc_patch_fw_mitigation_conduit so it can be re-used.
