mb/google/brya/var/vell: Fix camera LED flicker problem
Camera LED flicker 3 times or so as sensor is being probed
during kernel boot.
Configure _DSC to ACPI_DEVICE_SLEEP_D3_COLD so that driver skips
initial probe during kernel boot preventing camera LED flicker.
Corrects that by explicitly sequencing the reset GPIO and power GPIO
BUG=b:219644184
TEST=Build and boot on vell, observe whether camera LED flickers
