Bug description:
  [SRU Justifications]

  [Impact]

  Bug 2012407: kernel build fails without a newly learned directive in
  /sbin/dkms in bug 2012612 that helps identify whether a dkms modules
  is supposed to be built at all.

  Bug 2021740: To allow dkms driver installation initiated by ubuntu-
  drivers, packages must carry XB-Modaliases in debian/control.

  Bug 2026402: ipu6 dkms driver now fails to build against v6.5-rc1 and
  on.

  [Fix]

  * A BUILD_EXCLUSIVE_CONFIG patch for bug 2012407 was added to ivsc-
  driver/{jammy,lunar} because ivsc-driver/mantic has that already from
  bug 2012410. Also applied to ipu6-drivers/{mantic,lunar,jammy}.

  * Modaliases fixes for bug 2021740 was applied to ivsc-
  drivers/{mantic,lunar,jammy}, and ipu6-drivers/{mantic,lunar,jammy}

  * Additional fixes from upstream ipu6-drivers repo were added to
  ipu6-drivers/mantic for new hardware platforms.

  [Test Case]

  Bug 2012407: make sure intel-ipu6-dkms build will be skipped on
  platforms without CONFIG_VIDEO_V4L2_I2C, and intel-vsc-dkms on
  platforms without CONFIG_GPIOLIB_IRQCHIP, such as linux-headers-
  kvm/jammy.

  Bug 2021740: check built binary deb has XB-Modaliases tag in `dpkg-deb
  --info` output.

  For rest of the changes, they should be verified on next IPU6 equipped
  platform.

  [Where problems could occur]

  For changes for bug 2012407 and bug 2021740, they do no side effect to
  runtime system but to reinforce the interaction between other
  components.

  For rest of the changes, only in ipu6-drivers/mantic, they're to sync
  with upstream development for new hardware platforms, and expects bug
  fixes, updates in the coming development cycle.

  [Other Info]

  ========== original bug report ==========

  To be discovered by ubuntu-drivers, dkms packages should have
  modaliases tag in debian/control as possible.
