Add of_device_id table for Palma GPIO to be enable the
driver from DT file.
The driver can be registered from DT file as:
palmas: tps65913@58 {
:::::::::::
palmas_gpio: palmas_gpio {
compatible = "ti,palmas-gpio";
gpio-controller;
#gpio-cells = <2>;
};
};

Changes from V1:
Remove the ifdefs of CONFIG_OF around of_device_id structure for
defining compatible values.
