dt-bindings: gpio: mpc8xxx: Convert to yaml format

Convert binding doc from txt to yaml.

Remove redundated "gpio1: gpio@2300000" example.
Add gpio-controller at example "gpio@1100".

-* Freescale MPC512x/MPC8xxx/QorIQ/Layerscape GPIO controller
-
-Required properties:
-- compatible : Should be "fsl,<soc>-gpio"
-  The following <soc>s are known to be supported:
-       mpc5121, mpc5125, mpc8349, mpc8572, mpc8610, pq3, qoriq,
-       ls1021a, ls1043a, ls2080a, ls1028a, ls1088a.
-- reg : Address and length of the register set for the device
-- interrupts : Should be the port interrupt shared by all 32 pins.
-- #gpio-cells : Should be two.  The first cell is the pin number and
-  the second cell is used to specify the gpio polarity:
-      0 = active high
-      1 = active low
-
-Optional properties:
-- little-endian : GPIO registers are used as little endian. If not
-                  present registers are used as big endian by default.

-Example of gpio-controller node for a mpc5125 SoC:
