[PATCH v6 8/8] media: qcom: venus: add codec blacklist mechanism

[Erikas Bitovtas <xerikasxx@gmail.com>]

Add decode and encode blacklist properties to allow disabling different
codecs per Venus device, instead of doing it per HFI version.

Despite using HFI version 1, MSM8939 supports HEVC decoding, therefore
it is not blacklisted. Add HEVC to the type converter function so it can
be recognized.
