plat/arm/board/arm_fpga: Enable basic BL31 port for an FPGA image

This adds the minimal functions and definitions to create a basic
BL31 port for an initial FPGA image, in order for the port to be
uploaded to one the FPGA boards operated by an internal group within
Arm, such that BL31 runs as a payload for an image.

Future changes will enable the port for a wide range of system
configurations running on the FPGA boards to ensure compatibility with
multiple FPGA images.

It is expected that this will replace the FPGA fork of the Linux kernel
bootwrapper by performing similar secure-world initialization and setup
through the use of drivers and other well-established methods, before
passing control to the kernel, which will act as the BL33 payload and
run in EL2NS.

This change introduces a basic, loadable port with the console
initialized by setting the baud rate and base address of the UART as
configured by the Zeus image.

It is a BL31-only port, and RESET_TO_BL31 is enabled to reflect this.

stm32mp1: dynamically map DDR later and non-cacheable during its test

A speculative accesses to DDR could be done whereas it was not reachable
and could lead to bus stall.
To correct this the dynamic mapping in MMU is used.
A first mapping is done for DDR tests with MT_NON_CACHEABLE attribute,
once DDR access is setup. It is then unmapped and a new mapping DDR is done
with cacheable attribute (through MT_MEMORY) to speed-up BL33 (or OP-TEE)
load.

The disabling of cache during DDR tests is also removed, as now useless.
A call to new functions stm32mp_{,un}map_ddr_non_cacheable() is done
instead.

PLAT_XLAT_TABLES_DYNAMIC is activated globally as used in BL2 and BL32.

BL33 max size is also updated to take into account the secure and shared
memory areas. Those are used in OP-TEE case.

1. This removes hardcoded iomux/clk/addr configuration for debug uart,
provides possibility (as a workaround, till that information isn't
provided via DT) to set this configuration during compile time via
IMX_DEBUG_UART build flag.

Also for Colibri i.MX8QXP different pinmux configuration is applied
for UART3, FLEXCAN2_RX/TX pads are muxed to ADMA_UART3_RX/TX.

2. Having DEBUG_CONSOLE enabled without enabling DEBUG_CONSOLE_A35
doesn't make sense (since UART pinmux/clock configuration is applied
for UART only when DEBUG_CONSOLE_A35 is enabled. Check similar commit
for i.MX8QM 98a69dfd4a("plat: imx: imx8qm: apply clk/pinmux
