[Bug 2112375] Re: [SRU] Upgrade to 24.1 and add apusys firmware into linux-firmware-mediatek-genio deb package

Speaking as one member of the Technical Board, if this is the case, then
this doesn't meet the quality that our users expect from Ubuntu, so such
a change shouldn't go into Ubuntu at all. It can be delivered to
specific users who need it via a PPA or by resurrecting the partner
archive or similar.

released the new kernel that can be used in Noble earlier this month,
and we plan to support Noble in later this year.).

I don't think this is acceptable either. It would be really bad for
Ubuntu if, when we release 26.04, users start to learn that it isn't
really a release because support for stuff that Ubuntu supposedly has
(and had previously) isn't going to actually be included in that release
until later. Again: such things don't belong in Ubuntu itself.

Bug description:
  [ Impact ]

   * Bump firmware to MediaTek Rity 24.1

     This change include new firmware upgrade including WiFi/BT/SCP

   * Add apusys firmware

     This change include a new firmware to make APU work. APU is an AI
  hardware accelerator. It works with MediaTek's Neuron SDK to
  accelerate the computing process in AI applications. By adding this
  firmware, we will be able to use this accelerator.

   * Add valhall-1691526.wa

     valhall-1691526.wa is an additional firmware required by libmali on
  MediaTek Genio G510/G700 platform. By adding this firmware, we are
  able to enable gpu accesslator on G510/G700.

  [ Test Plan ]

   * Install linux-mtk (5.15.0-1039.47) from jammy-proposed repository

   * Install this new package

   * Boot to new kernel and check the dmesg message, you should find
  these messages:

  [ Other Info ]
   * This software is only for Ubuntu jammy, and we don’t want to fix a subsequent interim release now.
     This package is for MediaTek genio support project. Currently, the project does not plan to support non-LTS ubuntu release. And the support for noble is still in progress.
     So this SRU is only for jammy and can only be verified on jammy.

   * This update is a part of a group of package updating. Please hold these packages in proposed once it is approved. After all of them are approved, please copy into jammy-updates at same time.
