On imx51-babbage there is a 26MHz oscillator that is gated by GPIO3_1.

The output of this clock feeds audio codec clock and USB PHY clocks,
which are gated by GPIO4_26 and GPIO2_1 respectively.

Fix the clock representation by properly using gpio-gate-clock.

The clock nodes can be moved out of the 'clocks' node.

Based on a commit from Lucas Stach for imx51-zii-rdu1 board.

This also fixes the following build warning with W=1:

arch/arm/boot/dts/imx51-babbage.dtb: Warning (unit_address_vs_reg): Node /clocks/codec_clock has a reg or ranges property, but no unit name

Switch 2 has an 88e1545 PHY behind it, which is a quad PHY.  Only the
first three PHYs are used, the remaining PHY is unused.  When we wire
up the SFF sockets in a later commit, the omission of this causes the
fourth PHY to be used for port 3.  Specifying the PHYs in DT avoids
the auto-probing of the bus, and discovery of this PHY.

The interrupt specification for the GPIO expander is wrong - the
expander is wired to PTB28, which is GPIO98.  GPIO98 is on gpio chip
3, not 2.

In addition, the device is missing a required property.  Interrupt
controllers must have the "interrupt-controller" property specified.
Add this.

Improve the DTS files using lower case to fix the following dtc warnings:

Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format error, expected "<lower>"

Converted using the following command:

find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C

For simplicity, two sed expressions were used to solve each warnings separately.

To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before the
the opening curly brace:
