Bug Description

[SRU Justification]

[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.

[Test Plan]

1. Install the kernel from -proposed pocket along with linux-modules-{ipu6,ipu7,usbio,vision}-<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]

This is only mandatory for OEM platforms that shipped with an inverted module running linux-oem-6.17 and on. Nominate for ipu6-drivers/resolute, which is taken to be built along with linux-oem-6.17/noble.

========== original bug description ==========

Proposed fix in https://github.com/intel/ipu6-drivers/pull/427:

enabling new resolution 2888x1808 mode for OV05C10.
ov05c10 : add 2888x1808 init table
add GPIO dvdd for power control
IPU-bridge : add new link frequency for 2888x1808 mode
discrete : modify GPIO delay for CV-Himax's condition

This bug is awaiting verification that the linux-oem-6.17/6.17.0-1019.19 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-oem-6.17' to 'verification-done-noble-linux-oem-6.17'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.17' to 'verification-failed-noble-linux-oem-6.17'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
