[ Upstream commit 5f6bfab6da6531238e899fdf29efd6d0185adc3e ]

RK356x has Hantro G1 video decoder capable to decode MPEG2/H.264/VP8
video formats.

This patch adds support for RK356x family in existing Hantro
video decoder kernel driver.

Tested on [1] with FFmpeg v4l2_request code taken from [2]
with MPEG2, H.642 and VP8 samples with results [3].
