soc/intel/tigerlake: Disable image clocks 

TGL FSP does just pin mux for image clock pins by UPD and image clocks
are controlled by ACPI(camera_clock_ctl.asl) under tigerlake SOC folder.
Disable image clocks by UPD for bypassing FSP pin mux and do pin mux
in gpio.c according to board design.

BUG=none
BRANCH=none
TEST=Build and boot to OS
