[PATCH] dt-bindings: mmc: rockchip-dw-mshc: Fix the RV1103B compatible

From: Fabio Estevam <festevam at nabladev.com>

RV1103B uses the same DesignWare MSHC controller IP version as RK3576.

They have no "ciu-drive" nor "ciu-sample" clocks and use the phase
tuning inside the controller.

Fix it accordingly.
