Enable OV08X40 camera sensor for Intel MTL IPU6 MIPI Camera

[You-Sheng Yang]

[SRU Justification]

BugLink: https://bugs.launchpad.net/bugs/2060101

[Impact]

ov08x40 camera sensor is not working on IPU6 platforms.

[Fix]

A few changes from upstream kernel as well as a not yet upstreamed patch in the Intel ipu6-drivers GitHub repo.
* commit b1a42fde ("media: ov08x40: Avoid sensor probing in D0 state")
* commit eea8f730 ("media: ov08x40: Modify the tline calculation in different modes")
* https://github.com/intel/ipu6-drivers/blob/Release_20240624/patch/v6.8/0001-media-ov08x40-Add-Tline-calculation-and-handshake-pi.patch

[Test Case]

The proposed kernel should have been built along with the updated ipu6-drivers dkms. To verify ipu6-drivers alone, one will need experimental kernels from https://launchpad.net/~canonical-hwe-team/+archive/ubuntu/intermediate-kernel.

Here are steps for verifying kernels from -proposed pocket:

1. test camera after rebooting into a proposed kernel,
2. run suspend/resume stress test plan.
3. verify camera still working

[Where problems could occur]

These fixes are quite limited to ipu6/ivsc platforms, and affected no power-consumption or other noticible problem.

[Other Info]

The fixing commits/patches were meant for in-tree driver, but yet it changes device power up sequence and may affect platforms not interested in IPU6 enablement. It is then duplicated into ipu6-drivers dkms to avoid any unexpected side effect.

While some of the fixes are still under upstream review, meaning they're not yet available in any kernel release, linux-unstable/oracular/noble and oem-6.8/6.1x will be nominated for a rebuild against new dkms.

linux/oracular is still at 6.8.

too late for oem-6.5, let's focus on noble: linux/hwe-6.8

It's late but let's try to have this in oem-6.5 first because it'll take longer for the fix to land in hwe-6.8
