fix(versal-net): populate gic v3 rdist data statically
Currently gicv3_rdistif_probe() is called per CPU. In case of maxcpus=1,
only 1 core is initialized and gicr_base_addrs initialized for CPU 0
only. Because of this assertion is raised during Linux system suspend.
During Linux suspend, platform callback saves GIC v3 state which
internally invokes arm_gicv3_distif_pre_save(). This function tries to use
gicr_base for all CPUs. Since GICR base address for secondary CPUs are not
initialized, it raises assertion.
To fix the issue, populate GIC v3 rdist data statically (similar to Versal)
instead of dynamically initializing GIC v3 rdist per CPU.

feat(versal-net): add jtag dcc support
Add support for JTAG Debug Communication Channel(DCC), using the dcc
console driver, for Versal NET platform.
UART0/UART1 is not configured when the JTAG DCC is used as console for
the platform.
Though DCC is not using any UART, VERSAL_NET_UART_BASE needs
to be defined in the platform code. If its not defined, build errors
are observed.
Now VERSAL_NET_UART_BASE by default points to UART0 base.
Check for valid console(pl011, pl011_0, pl011_1, dcc) is
being done in the platform makefile, the error condition in
setting the value of VERSAL_NET_UART_BASE is redundant, thus the error
message is removed from the code.
This adds the ability to load the OP-TEE image via an SMC called from
non-secure userspace rather than loading it during boot. This should
only be utilized on platforms that can ensure security is maintained up
until the point the SMC is invoked as it breaks the normal barrier
between the secure and non-secure world.

Our system register access function wrappers are using "volatile"

since many system registers have side effects, and we don't want the
compiler to optimise or reorder them (what "volatile" prevents).
However this also naturally limits the compiler's freedom to optimise
code better, and those volatile properties don't apply to every type of
system register. One example are the CPU ID registers, which have
constant values, are side-effect free and read-only.
Introduce a new wrapper type that drops the volatile keyword, and use
that for the wrappers instantiating ID register accessors.
This allows the compiler to freely optimise those instructions away, if
their result isn't actually used, which can trigger further
