[PATCH v1 11/23] board: nbxv3: enable FlexSPI boot NOR (GD55LB02GF) and FIT boot

Enable the SPI controllers used on the module and attach the boot NOR:

 - &fspi (FlexSPI) supports the 256 MiB GigaDevice GD55LB02GF boot NOR
 - &dspi0 (lx2160a DSPI1, on module management SPI, already carrying the
   ZL30733 DPLL) and &dspi2 (DSPI3, it is the carrier general purpose SPI)
   are enabled.

SPI bus alias map, so the boot NOR is always `sf probe 3:0`:
 spi0 = &dspi0,
 spi2 = &dspi2,
 spi3 = &fspi.

defconfig: add the needed dependencies for loading FIT images.
