This removes the need to duplicate the configuration for each individual chip, but will instead pass on the configuration specified in the config attribute. Update nrf, stm32, rp macros with passing the config to a per-chip configure function which assumes the appropriate configuration to be passed to it. To demonstrate this feature, the stm32l0xx clock setup and RTC is added which exposes clock configuration different from stm32f4xx (and has a different set of timers and HAL APIs).
