* Add support for the STM32 encoder interface
* The STM32 only supports X2 and X4 modes.
* Enable interrupt handler on counter overflow
* Add simple test code for QDEC based on nucleo-f401 board

* Add support for the native encoder interface
* Native QDEC is there mostly for simulation
* Calling code will have to simulate QDEC increment/decrement

Changed the style of the UART configuration for different boards,
from a define based configuration to one based on an array of
structs, one struct for each UART, with the format of the struct defined
in cc2538/include/periph_cpu.h.
- Defined the fields of the struct in periph_cpu.h
- Removed the compilation includes that were in uart.c for each UART
- Implemented a generic ISR subroutine for clarity
- combined uart_base and uart_init in uart.c
- used bitmask for the interrupt setup
- took the uart Rx, Tx, and IRQ numbers out of the config
(as this has to match the .dev field). Replaced with
macros from the uart number
- took out some unused code
- implemented power on/off commands
- removed reset function - now bytes are just discarded on error
- Rx now not initialised if Rx callback = NULL, as per
drivers/periph/uart.h
- device is now enabled after callbacks are set, not before
- asserts raised if rts and cts are enabled for UART0
- BIT macro removed
Prevent CPU from using cortexm_init() when softdevice is used for NRF52 devices
as the softdevice already do some obscur inits
Also ensure the softdevice pkg will be used by hacking Makefile due to RIOT's
build system limitations (will be fix later with the new build system)
This function is supposed to be used for putting the CPU into
sleep mode for short amounts of time (e.g. in typical polling
loops used in periph drivers).
Rename 'cpu/efm32/families/efr32mg1p' module to 'cpu_efr32mg1p' to don't
conflict with 'cpu'.
Also required to set the path to vectors.o as its not provided by cpu.
