These drivers are GPIO drivers, and the do not need to use the
legacy header in <linux/gpio.h>, go directly for
<linux/gpio/driver.h> instead.
Replace any use of GPIOF_* with 0/1, these flags are for
consumers, not drivers.
Get rid of a few gpio_to_irq() users that was littering
around the place, use local callbacks or avoid using it at
all.

None of the Kconfigs for any of these drivers are tristate, meaning
that they currently are not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the drivers there is no doubt they are builtin-only. All
drivers get the exact same change, so they are handled in batch.
Changes are (1) use builtin_platform_driver, (2) use init.h header
(3) delete module_exit related code, (4) delete MODULE_DEVICE_TABLE,
(5) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags and (6)
drop ".remove" code and prevent sysfs unbind attempts to call ".remove".
Once this is done, the shared remove function in wmt.[ch] is no longer
used and hence it is removed as well.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE etc. tags since all that information
is already contained at the top of each file in the comments.

This patch adds support for the GPIO/pinmux controller found on the VIA
VT8500 and Wondermedia WM8xxx-series SoCs.
Each pin within the controller is capable of operating as a GPIO or as
an alternate function. The pins are numbered according to their control
bank/bit so that if new pins are added, the existing numbering is maintained.
All currently supported SoCs are included: VT8500, WM8505, WM8650, WM8750 and
WM8850.
