I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/61147
to look at the new patch set (#5).

mb/google/dedede/var/drawcia: Change power sequencing of Camera and VCM
Drawcia's MIPI camera sensor and VCM both share the same reset GPIO from the PCH. The current power sequence does not take this into account, and this leads to an unbalanced ref count of the reset GPIO, which can cause one or the other of the devices to reset unexpectedly.
This patch corrects that by explicitly sequencing the reset GPIO for both devices, which the builtin refcounting of this driver will automatically handle.
BUG=b:214665783 TEST=Build, boot to OS and check VCM once camera stream off
