[Stonking][PATCH 0/2] Support additional 2888x1808 at 30fps 900MHz for OVTI05C1 camera sensor

[You-Sheng Yang]

BugLink: https://bugs.launchpad.net/bugs/2147409

[Impact]

Camera sensor ov05c10 cannot be probed successfully because of
unsupported mode and link frequency is used:
```
[    3.435895] ov05c10 i2c-OVTI05C1:00: endpoint node not found
[    3.442834] ov05c10 i2c-OVTI05C1:00: endpoint node not found
[    3.448038] ov05c10 i2c-OVTI05C1:00: endpoint node not found
[    3.472394] ov05c10 i2c-OVTI05C1:00: endpoint node not found
[    3.477651] ov05c10 i2c-OVTI05C1:00: endpoint node not found
[    3.485219] ov05c10 i2c-OVTI05C1:00: endpoint node not found
[    3.493114] ov05c10 i2c-OVTI05C1:00: endpoint node not found
[    3.505769] ov05c10 i2c-OVTI05C1:00: no link frequency 900000000 supported
[    3.511491] ov05c10 i2c-OVTI05C1:00: probe with driver ov05c10 failed with error -22
```

[Fix]

Proposed fix in https://github.com/intel/ipu6-drivers/pull/427, which
has been merged into tag 20260327. This is later upstreamed as
f9536a8065d9 ("media: ipu-bridge: Add support additional link
frequency") and 844982d3b993 ("platform/x86: int3472: Increase handshake
GPIO delay to 200 ms").

[Test Plan]

1. Install the kernel from -proposed pocket along with
   linux-modules-{ipu6,ipu7}-<variant> meta packages.
2. Start camera streaming.
```
[    3.783964] intel_ipu7_isys.isys intel_ipu7.isys.40: bind ov05c10 2-0010 nlanes is 2 port is 0
[    3.784058] intel_ipu7_isys.isys intel_ipu7.isys.40: All sensor registration completed.
[    3.809310] intel_ipu7_psys.psys intel_ipu7.psys.40: IPU psys probe done.
```

[Where problems could occur]

This updates an not-yet-upstreamed camera sensor module ov05c10 along
with additional link frequency in the in-tree ipu-bridge supported
sensors list. Doesn't do anything if out-of-tree driver ov05c10 is not
loaded.

[Other Info]

Use upstreamed commits instead of the sauced patch from OOT dkms driver
repo for kernels >= v7.3~.
