gpio: mm-lantiq: use gpiochip data pointer
...
This makes the driver use the data pointer added to the gpio_chip
to store a pointer to the state container instead of relying on
container_of().

...
Instead of parsing manually the shadow content, use the much simpler
helper of_property_read_u32.

gpio: drop owner assignment from platform_drivers
...
A platform_driver does not need to set an owner, it will be populated by the
driver core.

GPIO: MIPS: lantiq: convert gpio-mm-lantiq to OF and of_mm_gpio
...
Implements OF support and convert to of_mm_gpio.
By attaching hardware latches to the External Bus Unit (EBU) on Lantiq SoC, it
is possible to create output only gpios. This driver configures a special
memory address, which when written to, outputs 16 bit to the latches.
