Let's only pull required headers, to avoid slowing compilation down.

Use the CameraSensor ID as the camera name in pipelines that uses a
CameraSensors, this is done in preparation of turning the camera name
into an ID. The CameraSensor ID meets the requirements that will be put
on camera ID.
Before this change example of camera names:
* OF based systems
ov5695 7-0036
ov2685 7-003c
* ACPI based systems
ov13858 8-0010
ov5670 10-0036
* VIMC
VIMC Sensor B
After this change the same cameras are:
* OF based systems
/base/i2c@ff160000/camera@36
/base/i2c@ff160000/camera@36
* ACPI based systems
\_SB_.PCI0.I2C2.CAM0
\_SB_.PCI0.I2C4.CAM1
* VIMC
platform/vimc.0 Sensor B
