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.

cpu/efm32/uart: uart_write(): block until TX is complete
...
This avoids breaking the last character if something unclocks
the UART immediately after uart_write() returns.
