Integrate HiSi video decoder support

This adds support for HiSi's video decoder support.

This commit does not contain the library blobs, as those
will be provided in a separate vendor package.

However this seems to gracefully fall back to software
decoding if the libraries aren't present or the kernel
doesn't support the vdec driver (like w/ 4.14+).
