spinand: call SPI setup_for_spinand if supported

Browse Source 
Call SPI setup_for_spinand() if supported and defined to configure the
SPI slave for the attached NAND. This is needed to configure the SPI
with the NAND page size and spare size for correct configuration of the
device.

Call it as soon as the NAND is detected to correctly handle SPI
controller with select_op_variant detection.
