The ov8865 driver as written expects a 24MHz input clock, but the sensor
is sometimes found on x86 platforms with a 19.2MHz input clock supplied.
Add a set of PLL configurations to the driver to support that rate too.
As ACPI doesn't auto-configure the clock rate, check for a clock-frequency
during probe and set that rate if one is found.

The ov8865 driver is one of those that can be connected to a CIO2
device by the cio2-bridge code. This means that the absence of an
endpoint for this device is not necessarily fatal, as one might be
built by the cio2-bridge when it probes. Return -EPROBE_DEFER if no
endpoint is found rather than a fatal error.

ov8865_state_init() calls ov8865_state_mipi_configure() which uses
__v4l2_ctrl_s_ctrl[_int64](). This means that sensor->mutex (which
is also sensor->ctrls.handler.lock) must be locked before calling
ov8865_state_init().
Note ov8865_state_mipi_configure() is also used in other places where
the lock is already held so it cannot be changed itself.
This fixes the following lockdep kernel WARN:

The OV5693 is a 5 Mpx CMOS image sensor, connected via MIPI CSI-2. The
chip is capable of a single lane configuration, but currently only two
lanes are supported.
Most of the sensor's features are supported, with the main exception
being the lens correction algorithm.
The driver provides all mandatory, optional and recommended V4L2 controls
for maximum compatibility with libcamera.

The MAX9286 has not explicitly declared a dependency upon VIDEO_V4L2.
While this dependency has likely always been met by configurations
including it, the device does use V4L2 core, and should depend upon it.
Add VIDEO_V4L2 as a dependency to match other drivers and prevent
failures when compile testing.
