variable rc is not initialized in the beginning of function
ipc_router_mhi_write and ipc_router_mhi_xprt_probe. This leads
possible use without initialization issue.

Decoder STOP command is to signal HW that this is the EOS
buffer. HW returns all the pending ETB's and FTB's. One of
the FTB_DONE's will have EOS flag back to client. With this,
driver don't need to support zero_bytes_used input buffers.

In boards without adv7481 chip present, there is a huge
boot time impact due to long time taken by probe failure
because of I2C communication failures. Add early returns
in case of error, to minimize the impact.

This change fixes an unclocked hdmi register access while going
to suspend state.
When splash is enabled on HDMI interface & we are going to turn
on the hdmi bridge power. Context of sde_hdmi connector is found
to be NULL because connector was not initialized yet and we never
called sde_hdmi_core_enable which enables hpd clocks.
Now when going to suspend system would be calling clock unprepare
for clocks which were never enabled. Hence hdmi clock gets unbalanced
and resulted in unclocked access to one of the hdmi register during
disabling vblank.
Adding struct sde_hdmi as a member of struct sde_hdmi_bridge and remove
dependency on sde connector to get the hdmi display object.
