arm64: dts: rockchip: Fix SD card controller probe on Pinephone Pro

Voltage constraints on vccio_sd are invalid. They don't match the voltages
that LDO9 can generate, and this causes rk808-regulator driver to fail
to probe with -EINVAL when it tries to apply the constraints during boot.

Fix the constraints to something that LDO9 can be actually configured for.
