[PATCH v2 15/15] rockchip: rk3328-orangepi-r1-plus: Enable boot from SPI NOR flash

[Jonas Karlman]

Add Kconfig options to enable support for booting from SPI NOR flash on
Orange Pi R1 Plus boards.

The generated bootable u-boot-rockchip-spi.bin can be written to 0x0 of
SPI NOR flash. The FIT image is loaded from 0x60000, same as on RK35xx
boards.

v2:
- Include SPI flash pinctrl nodes in SPL
- Enable SPI_FLASH_XMC and SPI_FLASH_ZBIT, zb25vq128 was reported on my
  R1 Plus LTS board.
