The Radxa Rock 4D exists also with a different SPI flash chip than the
one specified in the schematic[1]: XMC XM25QU128C.
At least board revision V1.12 can be impacted.
Enable CONFIG_SPI_FLASH_XMC Kconfig options.
Without this SPL fails to probe the SPI flash and thus fails to load
U-Boot proper from it.
Vendor U-Boot also enables CONFIG_SPI_FLASH_GIGADEVICE and
CONFIG_SPI_FLASH_WINBOND so other hardware configuration might exist.
They are not enabled by this patch.
