DDR less systems are possible for configuration like mini qspi
and making DDR region as normal memory may cause speculative
access which results u-boot hang if DDR is absent. So, this
patch fixes the issue by not making DDR memory region
entry into MMU table.
Future solution is to prepare MMU table per memory node in dts instead
of hard code DDR addresses.

This patch removes ifdef around mmio read and write rotuines
and make them a single routine by checking the current el.
This patch helps to remove ifdef around invoke_smc as well.

If PMUFW version is not v0.3 then panic.
ZynqMP switch to CCF based clock driver which requires
PMUFW to be present at certain version.

Define routines of mmio write and read functionalities
for zynqmp platform.
Also do not call SMC from SPL because SPL is running before ATF in EL3
that's why SMCs can't be called because there is nothing to call.
zynqmp_mmio*() are doing direct read/write accesses and this patch does
the same. PMUFW is up and running at this time and there is a way to talk
to pmufw via IPI but there is no reason to implement IPI stuff in SPL if
we need just simple read for getting clock driver to work.
Also make invoke_smc as global so that it can be reused in
multile places where ever possible.

Remove SECURE_IOU option which is not needed. U-Boot itself can detect

It also simplify usage because one Kconfig entry is gone.
