When it was running 'hello-world', the board could not be flashed through
JLinkExe anymore and only through the drag and drop support.
By resetting the board before doing 'loadbin' it can now be flashed
properly.
- Indicated that the hardware reset signal is used to reset the device and that
OpenOCD will that connect under reset
- Added troubleshooting for flashing using hardware reset
- Removed previous troubleshooting for flashing, as this issue is no longer
present since OpenOCD connects under reset
This removes doing `filter-out periph_hwrng, $(FEATURES_PROVIDED)`
after processing `cpu/$(CPU)/Makefile.features`.
The current solution is a HACK as `CPU_MODEL` is currently not available
at that moment but will be in the near future.
It will allow always including `cpu/$(CPU)/Makefile.features` after
`boards/$(BOARD)/Makefile.features`.
It is a part of moving `CPU/CPU_MODEL` definitions to `Makefile.features`.
UART devices are now configured using static array in header files instead of static variables in implementation to be able to define UART_NUMOF using the size of the array instead of a variable.
SPI devices are now configured using static array in header files instead of static variables in implementation to be able to define SPI_NUMOF using the size of the array instead of a variable.
I2C devices are now configured using static array in header files instead of static variables in implementation to be able to define I2C_NUMOF using the size of the array instead of a variable.
DAC pins are now configured using static arrays in header files instead of static variables in implementation to be able to define DAC_NUMOF using the size of these arrays instead of a variable.
ADC pins are now configured using static arrays in header files instead of static variables in implementation to be able to define ADC_NUMOF using the size of these arrays instead of a variable.
No need to specify SX127X_PARAMS structure as it is already
defined in drivers/sx127x/include/sx127x_params.h.
Also remove SX127X_PARAM_SPI and SX127X_PARAM_PASELECT as their
values are the same as default ones.

Moving atmega_stdio_init() to cpu_init() just before periph_init() guarantees
that stdio is available to allow DEBUG() in periph_init(). This also helps to
unify the boot up process of ATmega boards and de-duplicates the stdio init from
board_init().
