dt-bindings: soc: fsl: qe: Convert QE GPIO to DT schema

Browse Source 
Convert QE GPIO devicetree binding to DT schema. The old binding uses
fsl,<chip>-qe-pario-bank because multiple MCP83XX SoC has support for
these GPIO banks. The best practice is to list out every <chip> instead.

Note that "par_io" nodes are obsolete, and should not be used for
the new device trees. Instead, each Par I/O bank should be represented
via its own gpio-controller node:
Required properties:
- #gpio-cells : should be "2".
- compatible : should be "fsl,<chip>-qe-pario-bank",
"fsl,mpc8323-qe-pario-bank".
- reg : offset to the register set and its length.
- gpio-controller : node to identify gpio controllers.
Example:
qe_pio_a: gpio-controller@1400 {
#gpio-cells = <2>;
compatible = "fsl,mpc8360-qe-pario-bank",
"fsl,mpc8323-qe-pario-bank";
reg = <0x1400 0x18>;
gpio-controller;
};
qe_pio_e: gpio-controller@1460 {

"fsl,mpc8323-qe-pario-bank";
reg = <0x1460 0x18>;
gpio-controller;
};
