[PATCH 14/15] rockchip: rk3328-rock64: Enable boot from SPI NOR flash

[Jonas Karlman]

Add Kconfig options to enable support for booting from SPI NOR flash on
Pine64 Rock64.

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