support rtc PCF2131 for imx93.
Signed-off-by: Joy Zou <joy....@nxp.com>
---
Changes in v4:
1. remove arch/arm/dts/imx93_11x11_evk.dts change because it can sync from
kernel dts.
2. add the RTC support to the -u-boot.dtsi.
3. assign the rtc0 to rtc@53 in order to avoid date reset fail.
Changes in v3:
1. remove arch/arm/dts/imx93.dtsi modification because this change have existed.
Changes in v2:
1. use the flag bootph-pre-ram instead of uboot,dm-spl.
