cpu/efm32: fix DAC reference voltage configuration
...
The EFM32 MCU allows the reference voltage to be configured per DAC device, not per DAC channel. Also, the DAC reference voltage was defined in the configuration but not used anywhere.

cpu/efm32: fix PM configuration
...
`cpu/cortexm_common/include/cpu.h` has to be included in `cpu/efm32/periph_cpu.h` so that `PROVIDES_PM_SET_LOWEST` is defined if only `periph_cpu.h` is included. Otherwise `pm_set_lowest` is defined multiple times if the `pm_layered` module is not used. `PROVIDES_PM_OFF` has to be defined in case `pm_layered` is not used, e.g. in riotboot.

cpu/efm32: make series defines explicit
...
The EFM32 uses the provided _SILICON_LABS_32B_SERIES_0 and
_SILICON_LABS_32B_SERIES_1 definitions to enable or disable certain
code. With the introduction of new MCUs, there is also the
_SILICON_LABS_32B_SERIES_2 definition.
This PR ensures that the defines are explicit, and that #else
statements don't target the wrong series.
