This partially reverts commit b018be06f3 ("media: mediatek: vcodec:
Read max resolution from dec_capability").
After the previous patches:
- media: mediatek: vcodec: decoder: Fix 4K frame size enumeration
- media: mediatek: vcodec: decoder: Skip alignment for default resolution
- media: mediatek: vcodec: decoder: Fix resolution clamping in TRY_FMT
the max_{width,height} fields in |struct mtk_vcodec_ctx| no longer have
any real users. Remove them.

In commit b018be06f3 ("media: mediatek: vcodec: Read max resolution
from dec_capability"), TRY_FMT clamps the resolution to the maximum
that was previously set either by default 1080p or the limit set by a
previous S_FMT call. This does not make sense when doing TRY_FMT for
the output side, which may have different capabilities.
Instead, for the output side, find the maximum resolution based on the
pixel format requested. For the capture side, find the maximum
resolution based on the currently set output format.
The maximum resolution is found from the list of per-format frame
sizes, so the patch "media: mediatek: vcodec: dec: Fix 4K frame size
enumeration" is needed.

The default resolution of 64x64 is already aligned, according to the
call to v4l_bound_align_image() in mtk_vcodec_dec_set_default_params().
Drop the redundant v4l_bound_align_image() call. This also removes one
usage of ctx->max_{width,height}.

This partially reverts commit b018be06f3 ("media: mediatek: vcodec:
Read max resolution from dec_capability"). In this commit, the maximum
resolution ended up being a function of both the firmware capability and
the current set format.
However, frame size enumeration for output (coded) formats should not
depend on the format set, but should return supported resolutions for
the format requested by userspace.
Fix this so that the driver returns the supported resolutions correctly,
even if the instance only has default settings, or if the output format
is currently set to VP8F, which does not support 4K.
This adds an copy of special casing for !VP8 and 4K support. The other
existing copy will be removed when .max_{width,height} are removed from
|struct mtk_vcodec_ctx| in a subsequent patch.

The list of supported formats comes from helpers shared with the i.MX6
IPUv3 and is incorrect in multiple regards:
- 10-, 12- and 14-bit Bayer formats are stored in memory as SBGGR10,
SBGGR12 and SBGGR14 respectively (plus components permutations), not
SBGGR16. Same thing for greyscale formats.
- 16-bit RAW formats are not supported by the hardware.
Fix the supported formats table.

imx_media_of_add_csi() from imx-media-of.c validates that the fwnode for
the CSI bridge is enabled, and adds the fwnode to the async notifier of
the imxmd. The former is redundant, as if the CSI bridge driver probes,
clearly it is enabled in the DT. The latter is not needed as the imxmd
notifier isn't used anymore. The call is thus not needed and can be
dropped. This removes the dependency of imx7-media-csi.c on
imx-media-of.c.

The imx_media_dev framework maintains a per-pad list of connected video
devices, created once all subdevs have been bound. This is used for two
purposes, updating V4L2 control inheritance when links change, and
relaying subdev events to video nodes. None of these are used by the
imx7-media-csi driver as it implements the MC-centric approach. Drop
them.
