[PATCH 0/4][SRU][Noble] handle broken ACPI MIPI DisCo data

[You-Sheng Yang]

BugLink: https://bugs.launchpad.net/bugs/2070251

[Impact]

Multiple early IPU6 platforms may not have formal MIPI DisCo data
embedded in ACPI, and they may confuse latter driver and fail device
probing:

  ov01a10 i2c-OVTI01A0:00: can't get clock frequency
  ov01a10 i2c-OVTI01A0:00: failed to check hwcfg: -22
  ov01a10: probe of i2c-OVTI01A0:00 failed with error -22

[Fix]

A few commits from mainline kernel up to v6.10-rc5.

[Test Case]

Camera sensor device should then be probed correctly.

[Where problems could occur]

These fixes are based on MIPI DisCo support that is only available since
v6.8. For older kernels, the ipu6-drivers either has no hwcfg checking
implemented, or patched with DMI info to skip it.

[Other Info]

While the patches are from v6.10-rc5, only Noble and OEM-6.8 will be
nominated for fixing.
