e580d22f4a Use the external crystal on SAMD21 again. 
Also, re-enable calibration storage for CircuitPlayground Express.
Tested with a 500hz PWMOut on Metro M0 with Saleae:
 * with crystal 500hz
 * with usb 500hz +- 0.1hz
 * without either 487hz += 0.1hz

SAMD51 is skipped due to DFLL errata and the fact it defaults to a
factory calibrated 48mhz that works fine for USB.

Fixes #648

fd71e56891 atmel-samd: Re-org helper peripheral files into their own subdirectory. 
Ideally in the future they won't depend on ASF4 or MicroPython.
