xilinx: versal-net: Handle spi seq number based on boot device

Versal NET boards has QSPI and OSPI and default bus set to 0
is not working when system is booting out of OSPI which is
controller 1, as fixed aliases are set for all the boards
i.e., QSPI to 0 and OSPI to 1. Add controller autodetection
via spi_get_env_dev().
