arm64: dts: renesas: spider-cpu: Enable UFS device
Enable UFS device for R-Car S4-8 Spider CPU board.
Note that the conditions of RC21012 on the Spider are:
- OUT11 (for UFS30_REFCLK_V) is disabled as default.
- OUT11 is controlled by GPIO0 pin.
- The GPIO0 pin is inverted sense (low active) and pull-up enabled.
To output the clock, pin 4 of TCA9554 on the Spider board needs to
output low level so that using "gpio-gate-clock" for it.
