[U-Boot] [PATCH] db820c: add dummy clock for uart node

[Ramon Fried]

The missing clock causes serial_msm driver probe to fail.
Added a dummy node so the probe succeeds, as the clock init
currently in db820c is empty.

Fixes: 11d59fe5374a ("serial: serial_msm: fail probe if settings clocks fails")
