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.

Also disable OTAPDLYENA bit always as there is one issue in RTL

When linux calls pm_ioctl_set_pll_frac_mode() it doesn't expect the
fractional mode to be changed in hardware. Furthermore, even before this
patch setting the mode which is done by writing into register takes
no effect until the PLL reset is deasserted, i.e. until linux "enables"
the PLL. To adjust the code to system-level PLL EEMI API and avoid
unnecessary IPIs that would otherwise be issued, we buffer the mode
value set via IOCTL until the PLL mode really needs to be set.

stands for system-level communication (APU to PMU). Since linux
already uses a specific IOCTL function to do this and we need to
keep it that way, the pll clock ID given by linux has to be mapped
to the pll node ID that is communicated at the system-level (argument
of PLL set parameter API).
With this modification the function pm_api_clk_set_pll_frac_data is

Enforce full include path for includes. Deprecate old paths.
The following folders inside include/lib have been left unchanged:
- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}
The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).
For example, this patch had to be created because two headers were
called the same way: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.
Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

Ensure case clauses:
* Terminate with an unconditional break, return or goto statement.
* Use conditional break, return or goto statements as long as the end
of the case clause is unreachable; such case clauses must terminate
with assert(0) /* Unreachable */ or an unconditional __dead2 function
call
* Only fallthough when doing otherwise would result in less
readable/maintainable code; such case clauses must terminate with a
/* Fallthrough */ comment to make it clear this is the case and
indicate that a fallthrough is intended.
This reduces the chance of bugs appearing due to unintended flow through a
