clk: qcom: x1e80100-dispcc: Stop disp_cc_mdss_mdp_clk_src from getting parked
Parking disp_cc_mdss_mdp_clk_src at 19.2MHz causing the EFI GOP framebuffer
to stop functioning. The EFI GOP framebuffer should keep working until
the msm display driver loads, to help with boot debugging and to ensure
display output when the msm module is not in the initramfs.
Switch disp_cc_mdss_mdp_clk_src over to clk_rcg2_shared_no_init_park_ops
to keep the EFI GOP working after binding the x1e80100-dispcc driver.
