To support interrupt-based GPIO callbacks in the nRF5x series one needs
to use the GPIOTE module, which has a series of channels that can be
programmed to trigger interrupts on level changes.
This commit adds basic support for the GPIOTE module within the nRF5x
GPIO driver, as well as callback support in order for basic buttons and
switches to work.

PRIMARY, SECONDARY, NANOKERNEL, MICROKERNEL init levels are now
deprecated.
New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL
to replace them.
Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
where the documentation specified SECONDARY ran before the kernel started
up, but actually ran afterwards.

Don't use the previous reg value when setting up just one specific pin,
as it can have a side effect on other gpio pins.

NRF_GPIO_BASE can be used by both the nrf51 and nrf52 families, as it
gets defined by the nrf5x.h header files.

In 1.0 you could set only one callback on the whole gpio controller. It
was impossible for another sub-system to add another callback, without
overwritting an existing one.
Such API has been obsolete for a long time and no one is using it
anymore. Thus removing it entirely.
