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.)

9b4477e1dc Implement UART for 3.0 + related fixes.
1. UART: ported to ASF4. Allow rx-only and tx-only. Add .baudrate r/w property.

2. Make NeoPixel timing deterministic by turning off caches during NeoPixel writes.
3. Incorporate asf4 updates:
  a. async USART driver
  b. bringing Atmel START configuration closer to what we use
  c. Clock initialization order now specified by CIRCUITPY_GCLK_INIT_1ST and _LAST.
4. supervisor/port.c: Move commented-out clock-test pin setting to correct location.
