This commit adds SFC node for Radxa ROCK 5A. since sdhci and sfc on RK3588s share pins(i.e. exclusive), it cannot be enabled both nodes at the same time. so status = "okay" is omitted here.
you may be able to enable sfc (and disable sdhci) by fdt overlay. SPI NOR flash chip may vary, so use safe(lowest) spi-max-frequency.
