starting merge of stm32l code (thanks Armin!)
Merge branch 'stm32l-cc1101' of https://github.com/armint/dash7-ap-open-source-stack into merging-stm32

Conflicts:
	.gitignore
working on merge:
- build using cmake
- added toolchain config example (using gcc-arm-embedded toolchain)
TODO:
- CC1101 HAL driver currently depends on STM32L HAL driver and vice versa => refactor
- STM32L UART implementation does not compile currently, commented for now
phy_test compiles, links and can be deployed
correctly configure cflags for stm32l in cmake, fixes some compile errors in driverlib
applied patch by Armin, splitting stm32 SPI settings from general SPI function declarations
UART (USB) compiles now, not tested yet if logging works
explicitly set cmake linker language to c for HAL target (fixing cmake error message) + uncommented USB calls in UART implementation
