[PATCH 1/1] libcamera: libipa: camera_sensor: Add Sony IMX415 sensor properties

[Alexander Stein]

Provide the Sony IMX415 camera sensor properties and registration
with libipa for the gain code helpers.

The test patterns exposed by the IMX415 do not map well to the current
set of test pattern controls supplied by libcamera. These are left
intentionally unimplemented.

I shamelessly used the same commit message and structure from commit
6b1b2bd7 ("libcamera: libipa: camera_sensor: Add Sony IMX335 sensor
properties").
