The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The header with legacy struct of_mmio_gpio_chip and accompanying
APIs is called legacy-of-mm-gpiochip.h. Remove repetitive '.h'
at the end.

This is a rarely used feature that has nothing to do with the
client-side of_gpio.h.
Split it out with a separate header file and Kconfig option
so it can be removed on its own timeline aside from removing
the of_gpio consumer interfaces.

Commit 6aa7dbfa2877 ("gpio: mm-lantiq: use gpiochip data pointer") replaces
the use of container_of() with gpiochip_get_data(). However, the data
pointer is not yet set by the time the save_regs function is called.

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().

Since d621e8bae5ac9c67 (Create of_mm_gpiochip_remove), there is a
counterpart for of_mm_gpiochip_add.
This patch implements the remove function of the driver making use of
it.

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.
