rockchip: drop sdmmc speed limitation for RK3576/RK3588
The stability issue doesn't seem to be found on newer rockchip SoCs
like RK3528, RK3576 and RK3588, so drop the sdr50 limitation.
In addtion, the HS200 limitation for NanoPC T6 is also removed as
upstream fixed the real issue in mmc driver.

-Subject: [PATCH] arm64: dts: rockchip: lower mmc speed for Radxa Rock 5A
-
-The previously stated speed of sdr-104 in is too high for the hardware
-to reliably communicate with some fast SD cards.
-Rockchip boards have a common bug when operating uhs speed, which will
-hang the system during a soft reboot.
-
-To be on the safe side, lower the speed to workaround.
