clk: qcom: mmcc-sdm660: Add missing MDSS reset

Browse source

commit 0a0ea5541d upstream.

Add offset for display subsystem reset in multimedia clock controller
block, which is necessary to reset display when there is some
configuration in display controller left by previous stock (Android)
bootloader to provide continuous splash functionaluty.

Before 6.17 power domains were turned off for long enough to clear
registers, now this is not the case and a proper reset is needed to
have functioning display.
