9920f0a5de atmel-samd: Make ticks more atomic.
Always use current_tick when sub millisecond precision is required.
Otherwise getting the ms/us to correspond is tricky.

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

c0029e1d97 Don't lose half of the processor's serial number
Before this change, `microcontroller.cpu.uid` returned values
where the top 4 bits of each byte were zero, because of
an incorrect bitmask used in this function.

88aa0e2660 Remove SERCOM pointers from pin data structure because index is
enough.

This saves 380 bytes on the Arduino Zero build. (More pins ==
more savings.)

7292984204 Implement busio.I2c.
* Added asf4_conf/samd*/hpl_sercom_config.h
* Adjusted clocks in peripheral_clk_config.h.
* Put some frozen libs back in CPX for testing.
* Implement common-hal I2C
* Add samd*_peripherals.h in parallel with samd*_pins.h for common
  functions and data.
* Store SERCOM index in pins table for convenience.
* Canonicalize some #include guard names in various .h files.

simpler reset of SERCOMs; remove unused routine
