Sudeep Holla	6825f17c95	firmware: smccc: Export both smccc functions We need to export both arm_smccc_1_1_get_conduit and arm_smccc_get_version to allow several modules make use of them. Arm FFA, Arm SCMI and PTP drivers are few drivers that are planning to use these functions. Let us export them in preparation to add support for SCMI as module.

firmware: smccc: Export both smccc functions

We need to export both arm_smccc_1_1_get_conduit and arm_smccc_get_version
to allow several modules make use of them. Arm FFA, Arm SCMI and PTP
drivers are few drivers that are planning to use these functions.

Let us export them in preparation to add support for SCMI as module.

firmware: smccc: Add function to fetch SMCCC version

For backward compatibility reasons, PSCI maintains SMCCC version as
SMCCC didn't provide ARM_SMCCC_VERSION_FUNC_ID until v1.1.

PSCI initialises both the SMCCC version and conduit. Similar to the
conduit, let us provide accessors to fetch the SMCCC version also so
that other SMCCC v1.1+ features can use it.

firmware: smccc: Refactor SMCCC specific bits into separate file

In order to add newer SMCCC v1.1+ functionality and to avoid cluttering
PSCI firmware driver with SMCCC bits, let us move the SMCCC specific
details under drivers/firmware/smccc/smccc.c

We can also drop conduit and smccc_version from psci_operations structure
as SMCCC was the sole user and now it maintains those.

No functionality change in this patch though.
