mb/google/bluey: Configure GPIOs for USB camera

Configure and enable the GPIOs required for the USB camera. GPIO 10
(RESET_L) and GPIO 206 (ENABLE) are set as outputs and driven high
during mainboard initialization to ensure the camera is powered on
and ready for use by the OS.

Schematics version: 0.2

BUG=b:453773922
TEST=Verify detection of USB camera using `lsusb` in the OS.
