[ Upstream commit 3f0dadd230cc2630202a977fe52cd1dd7a7579a7 ]
Add the CLK_SET_RATE_PARENT flag to the CLK_VDO0_DP_INTF0_DP_INTF clock: this is required to trigger clock source selection on CLK_TOP_EDP, while avoiding to manage the enablement of the former separately from the latter in the displayport driver.
