Instead of adding sdma-ram-script-name into each board dts file, move
it to the SoC dtsi file instead.

Add alias for gpio nodes, so that gpio driver can identify the port
number and then specify a sensible gpio base rather than using the
one dynamically allocated by gpio core.

Some mxc processors have an edge_sel feature, which allows the IRQ to be
triggered by any edge.

This patch makes use of this feature if available, which skips mxc_flip_edge().

Change the value of #interrupt-cells of gpio nodes from 1 to 2, so that
the gpio irq type can be specified in device tree.  Also update binding
document to make it clear.

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.
