If hdmi i2c adapter is not deleted when hdmi bind failed, there
may be a crash when other device added. Because hdmi i2c memory
was freed but hdmi i2c still in the kobj list, its address may
be accessed when other device was added to the kobj list.

In drm_edid.c, yuv422 supported flag will be clean although EDID
indicates support for it. To be compatible with GKI, we can not
modify drm_edid.c. So we parse the information about yuv422 in EDID
in rockchip driver.

In tcpm displayport driver, drm_connector_oob_hotplug_event()
execute before dp_altmode_notify().
The dp_altmode_notify() call the mux set function, which
transfer phy info(lane count, pin assignments) to typec
phy.
The drm_connector_oob_hotplug_event() call oob_hotplug_event
function, which notify the cdn-dp driver hotplug event, and
the cdn-dp will start work to deal with the hotpug event,
which will user the phy info.
if here no delay time, The phy info use may be early than phy
info update, whick may cause the phy info mismatch.

Add a new drm_connector_oob_hotplug_event() function and
oob_hotplug_event drm_connector_funcs member.
On some hardware a hotplug event notification may come from outside the
display driver / device. An example of this is some USB Type-C setups
where the hardware muxes the DisplayPort data and aux-lines but does
not pass the altmode HPD status bit to the GPU's DP HPD pin.
In cases like this the new drm_connector_oob_hotplug_event() function can
be used to report these out-of-band events.
Avoid the conflict of GKI, the drm_connector_oob_hotplug_event() is be
completed in rockchip drm driver, not the drm framework.

L0 may be detected just in time if Gen1 training is finished.
But if EP supports higher Gen mode, Gen switch just happen
there but we keep on accessing devices, which leads unstable
link state and fail to detect the device finally.
And a bit more time before accessing devices to avoid this risky
case.
