Dynamic cfg: Do not populate args if already initialized

Dynamic cfg: Do not populate args if already initialized ...

This patch modifies the common utility function
`populate_next_bl_params_config()` to only modify the entrypoint arguments
to an executable image only if they are not initialized earlier.
This issue was detected while testing Optee on ARM platforms which needed
the current arguments to be preserved in the absence of corresponding
config files.

qemu: Accessing UART1 causes a data abort ...

The register address range of UART1 (crash console) are outside the
address ranges mapped for MMIO, resulting to an MMU abort when the
device registers are accessed.

Increase the size of DEVICE1 memory to include the range of UART1.

Remove sp_min functions from plat_common.c ...

This patch removes default platform implementations of sp_min
platform APIs from plat/common/aarch32/plat_common.c. The APIs
are now implemented in `plat_sp_min_common.c` file within the
same folder.

The ARM platform layer had a weak definition of sp_min_platform_setup2()
which conflicted with the weak definition in the common file. Hence this
patch fixes that by introducing a `plat_arm_` version of the API thus
allowing individual boards within ARM platforms to override it if they
wish to.

Fix FVP DRAM2 size ...

This was correct according to the model specifications , but it seems
that FVP doesn't implement it. It is safer to use the size exposed by
the DTB which is currently used by Linux.

Emit warnings when using deprecated GIC init ...

Emit runtime warnings when intializing the GIC drivers using the
deprecated method of defining integer interrupt arrays in the GIC driver
data structures; interrupt_prop_t arrays should be used instead. This
helps platforms detect that they have migration work to do. Previously,
no warning was emitted in this case. This affects both the GICv2 and GICv3
drivers.

Also use the __deprecated attribute to emit a build time warning if these
deprecated fields are used. These warnings are suppressed in the GIC
driver compatibility functions but will be visible if platforms use them.

Improve MULTI_CONSOLE_API deprecation warnings ...

For platforms that have not migrated to MULTI_CONSOLE_API == 1, there
are a lot of confusing deprecated declaration warnings relating to
use of console_init() and console_uninit(). Some of these relate to use
by the generic code, not the platform code. These functions are not really
deprecated but *removed* when MULTI_CONSOLE_API == 1.

This patch consolidates these warnings into a single preprocessor warning.
The __deprecated attribute is removed from the console_init() and
console_uninit() declarations.

For preprocessor warnings like this to not cause fatal build errors,
this patch adds -Wno-error=cpp to the build flags when
ERROR_DEPRECATED == 0.
This option (and -Wno-error=deprecated-declarations) is now added to
CPPFLAGS instead of TF_CFLAGS to ensure the build flags are used in the
assembler as well as the compiler.

This patch also disentangles the MULTI_CONSOLE_API and ERROR_DEPRECATED
build flags by defaulting MULTI_CONSOLE_API to 0 instead of
ERROR_DEPRECATED. This allows platforms that have not migrated to
MULTI_CONSOLE_API to use ERROR_DEPRECATED == 1 to emit a more meaningful
build error.

Finally, this patch bans use of MULTI_CONSOLE_API == 1 and AARCH32, since
the AArch32 console implementation does not support
MULTI_CONSOLE_API == 1.

Suppress spurious deprecated declaration warnings ...

Some generic compatibility functions emit deprecated declaration warnings
even when platforms do not use the deprecated functions directly. This
can be confusing. Suppress these warnings by using:
`#pragma GCC diagnostic ignored "-Wdeprecated-declarations"`

Also emit a runtime warning if the weak plat/common implemntation of
plat_get_syscnt_freq2() is used, as this implies the platform has not
migrated from plat_get_syscnt_freq(). The deprecated  declaration warnings
only help detect when platforms are calling deprecated functions, not when
they are defining deprecated functions.

FVP: Allow building for DynamIQ systems ...

FVPs that model DynamIQ configuration implements all CPUs in a single
cluster. I.e., such models have a single cluster with more than 4 CPUs.
This differs from existing default build configuration for FVP where up
to 4 CPUs are assumed per cluster.

To allow building for DynamIQ configuration, promote the macro
FVP_MAX_CPUS_PER_CLUSTER as a build option to have it set from the build
command line. The value of the build option defaults to 4.
