board: xilinx: versal-net: move platform_id/platform_version to .data

platform_id and platform_version are plain uninitialized statics,
placing them in .bss. U-Boot's linker script overlays .bss at the
same address as .rela.dyn (the relocation table), which is safe only
if nothing writes to .bss before relocation completes.

soc_detection() writes these variables during early board_init_f(),
well before relocation, corrupting live .rela.dyn entries. When
relocate_code() later reads the corrupted entry, it writes to an
invalid, unaligned address. QEMU 8.x tolerated this silently, QEMU
10.x enforces alignment checks and traps it, causing U-Boot to hang
right after printing "DRAM:  2 GiB", never reaching the console
prompt.

Move both variables to .data via __section(".data") so they no longer
share an address with the relocation table.
