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 rest of the unmigrated CONFIG symbols in the CONFIG_SYS_SDRAM
namespace do not easily transition to Kconfig. In many cases they likely
should come from the device tree instead. Move these out of CONFIG
namespace and in to CFG namespace.

We need to filter out NET_ETH_START errors because we have to enable
networking in order to propagate the MAC addresses to the DT while there
is no network driver for the prueth in U-Boot yet.

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.
