This avoids having to maintain to defconfigs that are 99% equivalent.
The approach is to use binman to generate two flash images,
flash-pg1.bin and flash-pg2.bin. With the help of a template dtsi, we
can avoid duplicating the common binman image definitions.

Due to different signature keys, the PG1 and the PG2 boards can no
longer use the same FSBL (tiboot3). This makes it impossible anyway to
maintaine a single flash.bin for both variants, so we can also split the
build.
A new target is added to indicates the build is for PG1 vs. PG2 boards.
Hence now the variants have separated defconfig files.
The runtime board_is_sr1() check does make no sense anymore, so remove
it and replace with build time check.
Documentation is updated accordingly. New binary artifacts are already
available via meta-iot2050.

The first AM6x device was the AM654x, but being the first we named it
just AM6, since more devices have come out with this same prefix we
should switch it to the normal convention of using the full name of the
first compatibility device the series. This makes what device we are
talking about more clear and matches all the K3 devices added since.

This converts the following to Kconfig:
CONFIG_SYS_SPL_MALLOC_SIZE
CONFIG_SYS_SPL_MALLOC_START
We introduce a default value here as well, and CONFIG_SYS_SPL_MALLOC to
control if we have a malloc pool or not.

- Make all users of CUSTOM_SYS_INIT_SP_ADDR reference SYS_INIT_SP_ADDR
- Introduce HAS_CUSTOM_SYS_INIT_SP_ADDR to allow for setting the stack
pointer directly, otherwise we use the common calculation.
- On some platforms that were using the standard calculation but did not
set CONFIG_SYS_INIT_RAM_SIZE / CONFIG_SYS_INIT_RAM_ADDR, set them.
- On a small number of platforms that were not subtracting
GENERATED_GBL_DATA_SIZE do so now via the standard calculation.
- CONFIG_SYS_INIT_SP_OFFSET is now widely unused, so remove it from most
board config header files.

This converts the following to Kconfig:
CONFIG_SPL_BSS_MAX_SIZE
CONFIG_SPL_MAX_FOOTPRINT
Note that the da850evm platforms were violating the "only use one" rule
here, and so now hard-code their BSS limit.

This converts the following to Kconfig:

Note that we need to make TPL_MAX_SIZE be hex, and so move and convert the
existing places.

This adds support for the IOT2050 Basic and Advanced devices. The Basic
used the dual-core AM6528 GP processor, the Advanced one the AM6548 HS
quad-core version.
Both variants are booted via a Siemens-provided FSBL that runs on the R5
cores. Consequently, U-Boot support is targeting the A53 cores. U-Boot
SPL, ATF and TEE have to reside in SPI flash.
