Subject: [PATCH v18, 00/19] Support multi hardware decode using of_platform_populate
This series adds support for multi hardware decode into mtk-vcodec, by first adding use
of_platform_populate to manage each hardware information: interrupt, clock, register
bases and power. Secondly add core work queue to deal with core hardware message,
at the same time, add msg queue for different hardware share messages. Lastly, the
architecture of different specs are not the same, using specs type to separate them.
This series has been tested with both MT8183 and MT8173. Decoding was working for both chips.
Patches 1~3 rewrite get register bases and power on/off interface.
Patches 4 export decoder pm interfaces.
Patches 5 add to support 8192.
Patch 6 support multi hardware.
Patch 7 separate video encoder and decoder document
Patch 8-17 add interfaces to support core hardware.
Patch 18-19 remove mtk_vcodec_release_dec/enc_pm interfaces.

Add prameter in pdata, for all platform will use compoent after mt8183

Must call component_master_add_with_match after platform_set_drvdata for component architecture.
