tools: give the driver control over CLKM (for ATmega32U2 boards)

Browse Source 
- include/atrf.h (atrf_set_clkm), lib/atrf.c (atrf_set_clkm): set or
  disable CLKM
- lib/driver.h (atrf_set_clkm_generic), lib/atrf.c (atrf_set_clkm_generic):
  generic function to set CLKM without restrictions
- lib/driver.h (struct atrf_driver): added driver operation "set_clkm"
  to set CLKM
- lib/atusb.c (atusb_set_clkm, atusb_driver): restrict CLKM on ATmega32U2
  boards
- atrf-txrx/atrf-txrx.c (init_txrx): use atrf_set_clkm to set CLKM
- atrf-txrx/atrf-txrx.c (init_txrx, main): pass CLKM frequency in MHz
  instead of code point
