Subject: [PATCH] arm64: dts: rockchip: rk3568: Add sfc a spi4 alias

Kernel's SFC is used for a private flash drivers not like
the standard one, but u-boot SFC is register as standard
spi, and the alias UCLASS_SPI id is required for part of
spi initialization progress. So kernel's alias is also
required when u-boot enable using kernel dtb case.
