spl_perform_fixups is redundant in the current implementation. SPLs call
dram_init during spl_enable_cache in arch/arm/mach-k3/common.c. In
U-Boot, dram_init and dram_init_banksize are automatically called in
init_sequence_f. Therefore, SPLs and U-Boot always determine the correct
RAM size. During Linux boot, fdt_fixup_memory_banks adjusts the RAM size
in the Linux device tree, ensuring correct RAM usage.
dram_init() calls get_ram_size() for the Verdin AM62, which determines
the correct RAM size through read/write operations. However, due to the
K3 bootflow placing ATF in RAM and requiring cache coherence, calling
get_ram_size() with caches enabled prevents ATF boot. Removing this call
restores ATF boot functionality.
This fixes a regression introduced in commit 4164289db8 ("board:
verdin-am62: fix missing memory fixup call") which prevents some of our
Verdin AM62 modules from booting.

Apalis/Colibri iMX6 V1.2 will replace the STMPE811 ADC/Touch controller
which is EOL by the TLA2024 ADC and AD7879 touch controller.
To support this new version, we detect the presence of the TLA2024
during boot and set a new environment variable named "variant". This
will allow us and users to select the correct DT easily.
By probing via I2C we have a robust detection method instead of relying
on the existing "board_rev" environment variable which is set by the
config block. Users can use "variant" in their DT selection and do not
have to map the board revision to a device tree.
"variant" environment variable behaviour:
* Empty or absent for all versions below v1.2 (STMPE811)
* "-v1.2" for all versions starting from v1.2 (TLA2024 + AD7879)
Usage example:
setenv fdtfile imx6q-apalis${variant}-${fdt_board}.dtb

The commit bc07851897 ("board: ti: Pull redundant DDR functions to a
common location and Fixup DDR size when ECC is enabled") broke DRAM
support for the Verdin AM62. This was partially fixed with commit
3f866c47b5 ("board: verdin-am62: add dram_init_banksize"). However,
because fixup_memory_node was not called, the Linux kernel was started
with the wrong memory size on modules with less memory available. This
resulted in boot failures. Fix this issue by calling fixup_memory_node
in the board file.
spl_perform_fixups will be called in the SPL and now sets the correct
memory size in the device tree of U-Boot by calling fixup_memory_node.
U-Boot will then adjust the memory sizes of Linux during bootm/booti in
fdt_fixup_memory_banks. This chain ensures that U-Boot and Linux only
use RAM that is actually available.

Add the dram_init_banksize function to the board file to properly set
DRAM memory sizes during boot.
The commit bc07851897 ("board: ti: Pull redundant DDR functions to a
common location and Fixup DDR size when ECC is enabled") relocated the
dram_init_banksize function from architecture specific initialization to
the TI board initialization code. As a result, boards relying on the
previous setup now require this function to be defined within their
board file to handle DRAM sizing correctly.
Without this function defined the following error appears during boot:
ERROR: Failed to allocate 0x1000 bytes below 0x0.

The Toradex configuration block is stored in the first boot partition of
the eMMC. After reading the configuration block, U-Boot switches back to
the user partition. Currently, this operation always targets mmc device
0, even when the configuration block is stored on mmc device 2.
This patch addresses the issue by switching the mmc device set in
CONFIG_TDX_CFG_BLOCK_DEV to the user partition, rather than using the
hardcoded device 0.

Simplify module version handling by removing the special case for the
Apalis iMX8QM.
The Apalis iMX8QM has been treated as a special case in module version
handling, but was always the default. By removing this special handling,
the code is simplified and easier to maintain.
We will not print the message "Unknown Apalis iMX8 module" anymore.
However, we still handle this because if the config block is missing we
show "MISSING TORADEX CONFIG BLOCK" and if the serial number is unknown
we show "Model: Toradex 0000 UNKNOWN MODULE V1.1A". Therefore, it is
still possible to detect such issues.
