[PATCH] riscv: dts: allwinner: Keep MQ Pro Wi-Fi powered during suspend

[khaliforce]

The RTL8723DS driver requests MMC_PM_KEEP_POWER during suspend.
The MQ Pro SDIO host lacks this capability.
The request returns -EINVAL and aborts suspend.

Add keep-power-in-suspend to the board's SDIO controller.

Tested on MangoPi MQ Pro.
RTC-triggered s2idle wake and Wi-Fi reconnection pass.
