907b4417c0 Add .baudrate support to ESP8266. 
busio.UART on ESP8266 provides a TX-only UART on GPIO2.
Fixed some bugs in the implementation.

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.

d02251f8cd Add a new board for Metro M4 Express Rev B. This is the board 
send to community members for testing.

Also tweaked and commented reset pin list for main Metro M4 Express
which is currently unreleased and is Rev D.

4710a2adba Compiles for m4. Untested on m0. 
This introduces a new spi_flash_api.h that works for both SPI and
QSPI. The previous spi_flash functions are now called external_flash
to minimize confusion.
