i2c: Make remove callback return void

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

drm/bridge: anx7625: Zero error variable when panel bridge not present

While parsing the DT, the anx7625 driver checks for the presence of a
panel bridge on endpoint 1. If it is missing, pdata->panel_bridge stores
the error pointer and the function returns successfully without first
cleaning that variable. This is an issue since other functions later
check for the presence of a panel bridge by testing the trueness of that
variable.

In order to ensure proper behavior, zero out pdata->panel_bridge before
returning when no panel bridge is found.

drm/bridge: anx7625: Use uint8 for lane-swing arrays

As defined in the anx7625 dt-binding, the analogix,lane0-swing and

reading the array as if it were of uint32 and masking to 8-bit before
writing to the registers. This means that a devicetree written in
accordance to the dt-binding would have its values incorrectly parsed.

Fix the issue by reading the array as uint8 and storing them as uint8
internally, so that we can also drop the masking when writing the
registers.

drm/bridge: Clear the DP_AUX_I2C_MOT bit passed in aux read command.

If the previous transfer didn't end with a command without DP_AUX_I2C_MOT,
the next read trasnfer will miss the first byte. But if the command in
previous transfer is requested with length 0, it's a no-op to anx7625
since it can't process this command. anx7625 requires the last command
to be read command with length > 0.

It's observed that if we clear the DP_AUX_I2C_MOT in read transfer, we
can still get correct data. Clear the read commands with DP_AUX_I2C_MOT
bit to fix this issue.
