Subrata Banik ae2e78ce31 mb/google/fatcat/var/moonstone: Configure CDCLK frequency for display
Configure the Core Display Clock (CDCLK) frequency selection by setting
the 'vga_cd_clk_freq_sel' register to 1 in the moonstone variant
overridetree. This ensures the display engine operates at the required
frequency (442Mhz) for the panel to meet the hardware configuration.

BUG=b:484559627
TEST=Build and boot google/moonstone, verify display initialization.
