arm64: dts: rockchip: Fix SD card support for RK3576 EVB1

When runtime suspend is enabled, the associated power domain is powered
off, which resets the registers, including the power control bit. As a result,
the card loses power during runtime suspend. The card should still be able
to process I/O with the help of mmc_blk_mq_rw_recovery(), which is suboptimal.
To address this issue, we must use vmmc-supply with a GPIO based method to
maintain power to the card. Also, add cd-gpios method to make hot-plug work
correctly during idle periods.
