arm64: dts: qcom: sm6350: Add MDSS_CORE reset to mdss

Like on other platforms, if the OS does not support recovering the state
left by the bootloader it needs access to MDSS_CORE, so that it can
clear the MDSS configuration. Add a reference to the relevant reset.

This also fixes display init on Linux v6.17.
