bc90a48ccf Add OF_prop_free function as a counterpart for OF_*prop_alloc
- Introduce new OF API function OF_prop_free to free memory allocated by
  OF_getprop_alloc and OF_getencprop_alloc. Current code just calls free(9)
  with M_OFWPROP memory class which assumes knowledge about OF_*prop_alloc
  functions' internals and leads to unneccessary code coupling

- Convert some of the free(..., M_OFWPROP) instances to OF_prop_free

Files affected by this commit are the ones I was able to test on real
hardware. The rest of free(..., M_OFWPROP) instances will be handled with
idividual maintainers

5a333f6f5f Add gpiokeys driver
gpiokey driver implements functional subset of gpiokeys device-tree bindings:
https://www.kernel.org/doc/Documentation/devicetree/bindings/input/gpio-keys.txt

It acts as a virtual keyboard, so keys are visible through kbdmux(4)

Driver maps linux scancodes for most common keys to FreeBSD scancodes and
also extends spec by introducing freebsd,code property to specify
FreeBSD-native scancodes.
