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

4140b3b944 atmel-samd: Stop double CSW after MSC reads 
This explicit zero length xfer leads to a second CSW packet. If
another read was started between the two CSWs then the host gets
confused and resets the device.

On reads, the CSW is automatically sent when we reply with the
total length. Writes must do it manually so they can wait for the
disk to flush the data.

cfbb74ffe7 atmel-samd: Reorder mpconfigport.mk and mpconfigboard.mk includes. 
This allows mpconfigport.mk to set this conditionally based on
$(CHIP_FAMILY).

268bf6f99e atmel-samd: Fix non-DEBUG USB cdc. 
I believe the issue was that LTO exacerbates a problem where a CDC
read is initiated but fails and leaves pending_read true
preventing further reads.

4aeef100f6 atmel-samd: More USB polish 
* Introduce a python script to generate the USB descriptor instead of
  a bunch of C macros. In the future, we can use this dynamically in
  CircuitPython.
* Add support for detecting read-only mass storage mounts.

Fixes #377
