Both were supported from the same source files, but this is clearly unclean and makes it more difficult to disable support for one or the other. Move these implementations into their own file, after adding the necessary private interfaces.

However the initial patch used the "select" Kconfig directive, which may result in the SCP module to not be compiled if remoteproc was disabled. In such a case, mtk-vcodec would try to link against non-existent SCP symbols. "select" was clearly misused here as explained in kconfig-language.txt. Replace this by a "depends" directive on at least one of the VPU and SCP modules, to allow the driver to be compiled as long as one of these is enabled, and adapt the code to support this new scenario. Also adapt the Kconfig text to explain the extra requirements for MT8173 and MT8183.
