[Impact]

Starting from kernel v6.8, Intel demands the use of in-tree VSC driver
instead of the out-of-tree dkms originated from
https://github.com/intel/ivsc-driver.

[Fix]

The in-tree vsc driver as of v6.8 still need a few fixes to archive the
same supportness to launched Intel IPU6 Camera devices. Commit 1,3, and
4 are to add supported devices and platforms. Commit 2 resolves an issue
after resumed.

[Test Case]

This is supposed to work together with the updated dkms, which shall
also be built along with the kernel itself as linux-modules-
ipu6-<variant>. Install the corresponding kernel/modules packages and
test camera functions.

[Where problems could occur]

While this is the first time we switch to in-tree VSC driver, and the
out-of-tree driver is not aligned at the time of transition and probably
never will, the provided functions and verified stability issues may
vary.

[Other Info]

The dkms is created to be compatible of multiple versions, yet the in-
tree vsc driver transitioning should only happen for kernel >= v6.8.
That is, oem-6.8, noble and linux-unstable will be nominated.

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

Starting from kernel v6.8 (yet from the code diff it's v6.6), Intel
demands the use of in-tree IVSC drivers instead of out-of-tree dkms from
https://github.com/intel/ivsc-driver.
