feat(zynqmp): add feature check support

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.

fix(zynqmp): use common interface for eemi apis

Currently all EEMI API has its own implementation in TF-A which is
redundant. Most EEMI API implementation in TF-A does same work. It
prepares payload received from kernel, sends payload to firmware,
receives response from firmware and send response back to kernel.

So use common interface for EEMI APIs which has similar functionality.
This will optimize TF-A code.

This patch disable the ITAPDLYENA bit for ITAP delay value zero.
As per IP design, it is recommended to disable the ITAPDLYENA bit

Also disable OTAPDLYENA bit always as there is one issue in RTL
where SD0_OTAPDLYENA has been wrongly connected to both SD0 and SD1
controllers. Hence it is recommended to disable OTAPDLYENA bit always
for both the controllers.
