  chips/samd21: Allow as few as one GPIO

This is probably mostly useful for testing new ports before
bothering to figure out all of the GPIO assignments.

  Log Message:
  -----------
  ao: Don't require a definition of HAS_BEEP

This comes from the origins of the ao code and doesn't
really apply in the snek world.

  chips/samd21: Fix XOSC configuration

Disable AMPGC (causes instability)
Stop sending XOSC to GCLK (DPLL gets it directly)
Remove frequency comments as they're misleading

  Log Message:
  -----------
  ports/snekboard: Run DPLL input at 62.5kHz instead of 1MHz

When run at 1MHz, the DPLL is unstable and causes troubles
when a panasonic distance sensor is plugged in. Instead,
run it as low as possible, which means 62.5kHz as the docs say
it wants something higher than 32kHz.
