rockchip: rk3568-rock-3a: Enable boot from SPI NOR flash
Add sfc and flash node to device tree and config options to enable
support for booting from SPI NOR flash on Radxa ROCK 3 Model A.
Unlike prior generation SoCs the BootRom in RK3568 can read all data and
look for idbloader at 0x8000, same as on SD and eMMC.
Use the rksd format and modify the mkimage offset to generate a bootable
u-boot-rockchip-spi.bin that can be written to 0x0 of SPI NOR flash. The
FIT image is loaded from 0x60000.
