Unify cpu_init for all Kinetis CPUs to reduce code duplication.
Updated the MCG driver implementation to make the configuration easier.
Most clock settings are initialized by kinetis_mcg_init() called from
cpu_init. Board specific external clock source initialization
(FRDM-K64F, PhyNode) needs to be performed in board_init instead of
in cpu_init.
The CPU has multiple issues and several parts of the platform code
does not even compile cleanly for this CPU in the current state.
This removes support for parts MK60DN256ZVLL10, MK60DN512ZVLL10
(note the Z) CPUs with this part number were used in Mulle v0.60 which
only has been used in some in-house projects at Eistec and LTU.
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.

- Use BITBAND_REG32 instead of BITBAND_REG for improved code readability.
- Remove BITBAND_PERIPH* from cpu-conf.h
- Remove BITBAND_REG from MK60D10.h, MK60DZ10.h
As discussed in #2725, this commit renames a number of stacksize constants to
better convey their intended usage. In addition, constants for thread priority
are given a `THREAD_` prefix. Changes are:
* KERNEL_CONF_STACKSIZE_PRINTF renamed to THREAD_EXTRA_STACKSIZE_PRINTF
* KERNEL_CONF_STACKSIZE_DEFAULT renamed to THREAD_STACKSIZE_DEFAULT
* KERNEL_CONF_STACKSIZE_IDLE renamed to THREAD_STACKSIZE_IDLE
* KERNEL_CONF_STACKSIZE_MAIN renamed to THREAD_STACKSIZE_MAIN
* Move thread stacksizes from kernel.h to thread.h, since the prefix changed
* PRIORITY_MIN renamed to THREAD_PRIORITY_MIN
* PRIORITY_IDLE renamed to THREAD_PRIORITY_IDLE
* PRIORITY_MAIN renamed to THREAD_PRIORITY_MAIN
* Move thread priorities from kernel.h to thread.h since the prefix has changed
* MINIMUM_STACK_SIZE renamed to THREAD_STACKSIZE_MINIMUM for consistency
Tested on the following Freescale Kinetis K60 CPUs:
- MK60DN512VLL10
The port should with a high probability also support the following variations of the above CPUs (untested):
- MK60DN256VLL10
And possibly also:
- MK60DX256VLL10
- MK60DX512VLL10
- MK60DN512VLQ10
- MK60DN256VLQ10
- MK60DX256VLQ10
- MK60DN512VMC10
- MK60DN256VMC10
- MK60DX256VMC10
- MK60DN512VMD10
- MK60DX256VMD10
- MK60DN256VMD10
Currently not working on the following CPUs (Missing PIT channel
chaining necessary for kinetis_common/periph/timer implementation):
- MK60DN256ZVLL10
- MK60DN512ZVLL10
- MK60DX256ZVLL10
- MK60DX512ZVLL10
- MK60DN512ZVLQ10
- MK60DN256ZVLQ10
