This API returns version of supported APIs.
Here, there are three cases to check API version by using feature
check implementation.
1. Completely implemented in TF-A: I mean the EEMI APIs which are
completely implemented in the TF-A only. So check those IDs and
return appropriate version for the same. Right now, it is base
version.
2. Completely implemented in firmware: I mean the EEMI APIs which are
completely implemented in the firmware only. Here, TF-A only passes
Linux request to the firmware to get the version of supported API. So
check those IDs and send request to firmware to get the version and
return to Linux if the version is supported or return the error code
if the feature is not supported.
3. Partially implemented (Implemented in TF-A and firmware both):
First check dependent EEMI API version with the expected version in
the TF-A. If the dependent EEMI API is supported in firmware then
return its version and check with the expected version in the TF-A.
If the version matches then check for the actual requested EEMI API
version. If the version is supported then return version of API
implemented in TF-A.
