Currently, UART configuration is populated for few
SEs(Serial engine) only in sa8775p DTSI file.

Populate UART configurations of remaining SEs for sa8775p soc.

I think this is a long standing tradition of adding UART configuration
only to those nodes that actually will be used for UART on one or
another device. Is this the case for all these UART nodes?

Recently, we have begun adding all possible UART configurations, similar 
to what we’ve done with I2C and SPI.
We will continue this approach for future targets.

Please describe why it is done, not what is being done by the patch. In other words, why do you need all uarts in this case.
