of_match_device could return NULL, and so cause a NULL pointer
dereference later.

Make of_device_id array const, because all OF functions
handle it as const.

The site-specific OOM messages are unnecessary, because they
duplicate the MM subsystem generic OOM message.

This switches the two members of struct gpio_chip that were
defined as unsigned foo:1 to bool, because that is indeed what
they are. Switch all users in the gpio and pinctrl subsystems
to assign these values with true/false instead of 0/1. The
users outside these subsystems will survive since true/false
is 1/0, atleast we set some kind of more strict typing example.

It seems that the value read back from the PALMAS_GPIO_DATA_IN register
isn't valid if the GPIO direction is out.  When that's the case, we can
read back the PALMAS_GPIO_DATA_OUT register to get the proper output value.

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>;
		};
