arm64: dts: rockchip: Lower sd speed on rk3566-soquartz
[ Upstream commit 5912b647bd0732ae8c78a6e5b259c82efd177d93 ]
Just like the Quartz64 Model B the previously stated speed of sdr-104
in soquartz is too high for the hardware to reliably communicate with
some fast SD cards.
Especially on some carrierboards.
Lower this to sd-uhs-sdr50 to fix this.
