media: meson: vdec: bring up to compliance

Add all the necessary bits to pass v4l2-compliance in stateful decoding
mode.

Mostly includes tracking the state of the decoder, allowing the OUTPUT
queue to stream while the CAPTURE queue is inactive, handling resolution
change events, draining with V4L2_DEC_CMD_STOP, copying more metadata
from the src buffers to the dst buffers, etc.

media: meson: vdec: add g12a platform

Add support for the G12A platform by:
- adding the G12A codec support, here MPEG1 & MPEG2
- getting the new hevcf clock for the upcoming HEVC/VP9 decoding support

media: meson: add v4l2 m2m video decoder driver

Amlogic SoCs feature a powerful video decoder unit able to
decode many formats, with a performance of usually up to 4k60.

This is a driver for this IP that is based around the v4l2 m2m framework.

It features decoding for:
- MPEG 1
- MPEG 2

Supported SoCs are: GXBB (S905), GXL (S905X/W/D), GXM (S912)

There is also a hardware bitstream parser (ESPARSER) that is handled here.
