clk: qcom: dispcc-eliza: Fix disp_cc_mdss_mdp_clk_src RCG stall on Eliza EVK
Eliza EVK (eliza-cqs-evk.dts) does not have display enabled, however its
Display Clock Controller is enabled and references parent clocks from
DSI PHYs, which causes clock reparenting issues during probe (init) and
warning on Eliza EVK:
disp_cc_mdss_mdp_clk_src: rcg didn't update its configuration.
