drivers/cc110x: Moved cc110x_params.h from boards to driver

 - Replaced magic numbers in the CC110X configuration of the MSBA2
   with SPI_DEV(x) and GPIO_PIN(x, y) macros
 - Adjusted implementation of `cc110x_params.h` to match the code of `at86rf2xx`
 - Made MSBA2's CC110X parameters the default configuration
