Move DRAM bank detection from fdtdec to custom implementation to
ensure memory banks are populated before get_page_table_size() is
called during MMU initialization.
The current fdtdec-based approach populates gd->bd->bi_dram[] too
late in the boot sequence, causing get_page_table_size() to be
called with unpopulated DRAM information. This prevents dynamic
page table sizing based on actual memory configuration.
Parse /memory nodes in dram_init() to fill versal2_mem_map[]
early enough for MMU setup. Supports up to
CONFIG_NR_DRAM_BANKS (36) non-contiguous banks with high memory
regions (>4GB) and use __weak get_page_table_size implementation
to estimate page table size based on the populated DRAM banks.

The eMMC boot device controller on Versal2 requires device pointer
initialization before accessing its sequence number. The EMMC_MODE case
was using dev_seq(dev) on an uninitialized pointer, causing corrupted
boot_targets entries (mmc7f7fbfbf instead of mmc0/mmc1).
Add uclass_get_device_by_name() call to properly initialize the device
pointer before reading the sequence number. The dev sequence number is
determined at runtime based on DT aliases.
Fix boot_targets corruption in eMMC boot mode, allowing proper boot
device selection instead of falling back to JTAG mode.

Add support for loading the secure & non-secure pdi images and PL
bitstream on the Versal Gen2 platform. The FPGA driver is enabled
to load the bitstream in PDI format on the AMD Versal Gen2 device.
PDI is the new programmable device image format for Versal Gen2,
and the bitstream for the Versal Gen2 platform is generated exclusively
in this format.
With the enhanced SMC format in TF-A ensuring transparent payload
forwarding for Versal Gen2, the u-boot driver must now handle the
word swapping of PDI address that was previously done in TF-A for
this API. The source code for the Versal2 loadpdi command and the
CONFIG_CMD_VERSAL2 configuration has been removed. It now utilizes
the fpga load <dev> <address> <length> command to load secure &
non-secure pdi images.

After adding the U_BOOT_LONGHELP macro some new commands came in still
that were not making use if it. Switch these cases over and in a few
places add missing newlines as well.
