arm64: versal: Define distro boot commnads for qspi ospi and mmc

This patch adds distro boot commands for qspi, ospi and mmc.
The distro boot commands now reads the script from flash offset
of 63.5MB  for qspi and ospi and executes it. For mmc its same
as generic distro boot command. As either one of the qspi or ospi can
exist on hardware, defined a single distroboot command as xspi
that works for both.

Setup default location via script_offset_f to 63.5MB to match the most
xilinx reference boards for qspi, ospi for now.
512kB allocated space for script size (script_size_f) should be more
than enough to cover custom boot logic.
