feat(versal-net): remove empty crash console setup

Private plat_crash_console_init() has all the setup commented
that's why it was never been tested.
pl011 uart is supposed to be used as crash console and it should be
enought to add CONSOLE_FLAG_CRASH and remove platform specific
implementation and use generic one.
Early console can't be used for early ASM debugging but that's
expected and not required.
