drm/bridge: Pass down connector to drm bridge detect hook
In some application scenarios, we hope to get the corresponding
connector when the bridge's detect hook is invoked.
In most cases, we can get the connector by drm_atomic_get_connector_for_encoder
if the encoder attached to the bridge is enabled, however there will
still be some scenarios where the detect hook of the bridge is called
but the corresponding encoder has not been enabled yet. For instance,
this occurs when the device is hot plug in for the first time.
Since the call to bridge's detect is initiated by the connector, passing
down the corresponding connector directly will make things simpler.

drm: bridge: adv7511: remove s32 format from i2s capabilities
The ADV7511 chip allows 24 bits samples max in I2S mode, excepted for
direct AES3 mode (SNDRV_PCM_FORMAT_IEC958_SUBFRAME_LE format).
However the HDMI codec exposes S32_LE format as supported.
Adapt ADV7511 HDMI I2S format list to expose formats actually supported.

The host_node pointer was assigned and freed in adv7533_parse_dt(), and
later, adv7533_attach_dsi() uses the same. Fix this use-after-free issue
by dropping of_node_put() in adv7533_parse_dt() and calling of_node_put()
in error path of probe() and also in the remove().
