[PATCH 1/2] OMAP2+: UART: Fix incorrect population of default uart pads

["Govindraj.R" <govindraj.raja@xxxxxx>]

From: "Govindraj.R" <govindraj.raja@xxxxxx>

The following commit:
(7496ba3  ARM: OMAP2+: UART: Add default mux for all uarts)
added default pads for all uarts. But not all boards tend to
use all uarts and most of unused uart pins are muxed for
other purpose. This commit breaks the modules which where trying
to use unused uart pins on their boards.

So remove the default pads adding.
