Subject: [PATCH v3 0/2] media: mtk-vcodec: fix builds when remoteproc is disabled

Thanks everyone for the feedback on v2. This version has grown a little bit, but
most of the added lines is just code moving around to new files. All in all this
certainly makes the driver a little bit cleaner.

Tested on both MT8173 and MT8183 and confirmed that the decoder was working on
both.

Changes since v2:
* Use the FOO || !FOO magic suggested by Hans to ensure a built-in module does
  not try to link against symbols in a module,
* Added a patch to split the VPU and SCP ops into their own source files and
  make the optional build cleaner,
* Control the build of firmware implementations using two new transparent
  Kconfig symbols.

Changes since v1:
* Added Acked-by from Randy.
* Fixed typo in Kconfig description.

  media: mtk-vcodec: fix build breakage when one of VPU or SCP is
    enabled
