[PATCH v4,03/11] media: mediatek: vcodec: Removing struct 'mtk_vcodec_ctx/dev' for shared interface

[Yunfei Dong]

The shared struct 'mtk_vcodec_ctx/dev' will be changed to 'mtk_vcodec_enc_ctx/dev'
and 'mtk_vcodec_dec_ctx/dev' in order to separate encoder and decoder. Removing
common struct 'mtk_vcodec_ctx/dev' for shared interface which encoder and decoder
used at the same time. Then encoder and decoder can call the same interface
independently.
