142c28094e kinetis_common: Refactor GPIO implementation 
This is a rewrite of the Kinetis GPIO driver which follows the
refactored API in [1]. Pins are specified using the GPIO_PIN(PORT_x, y)
macro, e.g. GPIO_PIN(PORT_E, 25) for the PTE25 pin.

The interrupt pin handling is now implemented as a linked list, this
is more memory efficient, but with a minor variation in interrupt
latency depending on in what order the pins were initialized at
runtime.

Because the linked list entries are taken from a shared pool, there is
also the possibility of running out of available configuration slots,
define the preprocessor macro GPIO_INT_POOL_SIZE in periph_conf.h if
you need more than 16 pins configured for interrupts in the same
application.

c404bd97ad k60: Add workaround for errata e4218 
e4218: SIM/FLEXBUS: SIM_SCGC7[FLEXBUS] bit should be cleared when the
FlexBus is not being used.

Errata type: Errata

Description:

The SIM_SCGC7[FLEXBUS] bit is set by default. This means that the
FlexBus will be enabled and come up in global chip select mode. With
some code sequence and register value combinations the core could
attempt to prefetch from the FlexBus even though it might not actually
use the value it prefetched. In the case where the FlexBus is
unconfigured, this can result in a hung bus cycle on the FlexBus.

Workaround:

 - If the FlexBus is not being used, disabled the clock to the FlexBus
   during chip initialization by clearing the SIM_SCGC7[FLEXBUS] bit.
 - If the FlexBus will be used, then enable at least one chip select as
   early in the chip initialization process as possible.

f0e7d2fc03 cpu/kinetis_common/timer.c: cleanup and fix the pit timer 
It simplifies the virtual "count up timer" and improves
the accuracy a little. The LDVAL for the prescaler should
be set as a number of prescaler cycles-1. The virtual
up-counter should be corrected in the isr by +1
(See PIT reference manual). This also fixes a bug where
the timer is not used by xtimer and up-counter does not overflow.

1f98e06956 samd21/gpio: check if interrupt is enabled in isr, fixes #4087 
The interrupt flag for a previously configured external gpio interrupt
will be set regardless of the actual configuration. So when another source
causes an interrupt, the callback of a disabled gpio interrupt will be serviced
although it was disabled if the interrupt occured in the meantime.
