I still have some work to do. I had to realize that the EFM32GG family does not have the USHFRCO clock that is used as USB_CLK on EFM32GG12B. That means we have to use different clock sources for different families 😟

`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.

Not much time for reviewing, but testing I can fit in, on stk3700 and a custom board.

@chrysn Is there a chance you could test it on your stk3700 board? It's already reviewed and tested on EFM32GG12, just to know whether it also works for EFM32GG.

Tested with stk3700:

$ make -C tests/usbus_hid BOARD=stk3700 PROGRAMMER=openocd all flash term
2022-12-19 09:50:36,417 # main(): This is RIOT! (Version: 2023.01-devel-470-gc6bae-drivers/usbdev_synopsys_dwc2_efm32)
2022-12-19 09:50:39,166 # RIOT USB HID echo test
2022-12-19 09:50:39,169 # Write input to the hidraw device under /dev/hidrawX, and see if it gets echoed here

$ echo foo | sudo tee /dev/hidraw0
foo

2022-12-19 09:54:37,783 # USB_HID rx_cb: Test argument 
2022-12-19 09:54:37,784 # Msg received via USB HID: 
2022-12-19 09:54:37,785 # foo
2022-12-19 09:54:37,785 #

Confirming that this works on stk3700. Thanks a lot!

What's missing to get all lights green? "bors merge" or "bors try" or anything else?

Ah, and @jue89 has not cleared his review position. (Weird, I'd like to click "re-request review" but don't find the button).

Juergen, are you happy with the responses to your earlier review? Please update it.
