feat(versal2): add hooks for mmap and early setup

Add early setup hooks through custom_early_setup() and provide a
mechanism to support custom memory mapping, including the extension
of the memory map via custom_mmap_add(). This change may also
require alignment of the MAX_XLAT_TABLE and MAX_XLAT_TABLES macros.
These can be defined within the custom_pkg.mk makefile as follows:

MAX_MMAP_REGIONS := XY
$(eval $(call add_define,MAX_MMAP_REGIONS))
MAX_XLAT_TABLES := XZ
$(eval $(call add_define,MAX_XLAT_TABLES))

If PLATFORM_STACK_SIZE is not already defined, a default value
should be used. This allows for configurability of the stack size
across different interfaces, such as custom packages. The
custom_early_setup() function enables early low-level operations
to bring the system into a correct state. Support for a custom
SiP service is also added. A basic implementation of
custom_smc_handler() is provided by the platform, while the actual
definition is expected to be supplied by the custom package. This
feature is designed for use by external libraries, such as those
that require status checking. This code introduces a generic
framework for integrating custom logic via the
$(CUSTOM_PKG_PATH)/custom_pkg.mk makefile, including
optional support for custom SMC functionality, which is determined
by the custom package.

refactor(versal2): add tfa_no_pm flag for scmi

Added the TFA_NO_PM flag in the SCMI file and guarded SCMI
functionality with if conditions. When TFA_NO_PM is set to 0
(default), Platform Management is enabled. When set to 1, Platform
Management is disabled. This allows the generic SCMI driver to be
used in non-PM scenarios while maintaining compatibility with
conforming power management interfaces.

feat(versal2): extended SMCCC payload for EEMI

Until Versal, the extended SMCCC payload was supported only for
QUERY_DATA, while other APIs used the legacy SMCCC format.

In Versal Gen 2, all EEMI APIs are supported with extended SMCCC
payload only, enabling a simplified and efficient pass-through
implementation.

Also, set TFA_NO_PM to 0 to enable power management by default.

fix(versal2): typecast expressions to match data type

This corrects the MISRA violation C2012-10.4:
Both operands of an operator in which the usual arithmetic
conversions are performed shall have the same essential type
category.
The condition is explicitly checked against 0U, appending 'U' and
typecasting for unsigned comparison.

feat(versal2): add support for AMD Versal Gen 2 platform

New SoC is a78 based with gicv3 and uart over pl011. Communication
interfaces are similar to Versal NET platform. System starts with AMD PLM
firmware which loads TF-A(bl31) to memory, which is already configured, and
jumps to it. PLM also prepare handoff structure for TF-A with information
what components were load and flags which indicate which EL level SW should
be started.
