dt-bindings: backlight: qcom-wled: Fix bouncing email addresses

Bjorn is no longer at Linaro. Update his email address to @kernel to
match the .mailmap entry.

The servers for @codeaurora are long retired and messages sent there
will bounce. Update Kiran's email address to match the .mailmap entry.

This will help anyone that is looking to reach out about this binding
and is not using .mailmap to pre-process their message.
