Change the indentation for property fsl,pins a little bit, so that
the first and the last line get the same indentation with all other
lines.  Then it will be easier to copy and past any of these lines.

In order to have audio functional on mx6qsabrelite, it is necessary
to setup the IOMUX for MX6Q_PAD_GPIO_0__CCM_CLKO pins as it provides
the audio clock.

Imx6q sabrelite board uses ecspi1 to connect a spi flash sst25vf016b,
we need to add pinctrl information for it in the dts, otherwise the
ecspi1 driver can't work and the connected flash is wrongly
detected as a mr25h256 flash like this:

m25p80 spi32766.0: found mr25h256, expected sst25vf016b
m25p80 spi32766.0: mr25h256 (32 Kbytes)

It has been pointed out by device tree maintainer for several times
that the generic names 'serial' and 'ethernet' should be used for
those devices per ePAPR.  Renames imx uart and fec device tree nodes
to stop them being bad examples.
