Remove SERCOM pointers from pin data structure because index is
...
enough.
This saves 380 bytes on the Arduino Zero build. (More pins ==
more savings.)

Check usb_busy up front in usb background function.

Hopefully fixes #655 but we'll let @jerryneedell confirm.

Correct NO_TIMER index value for SAMD21.
...
We check validity by ensuring it's lower than the total number of
timers. 0 is a terrible number for the NO_TIMER value because its
valid even though it shouldn't be.

Move usb read finish into interrupt.
...
Having the `active_read = false` in the background function left
a chance that a new_write occurs before active_read is set to false.
In that case, we'll read the appropriate data rather than write it
and never clear the active write.
Hopefully fixes #655 .

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.

Correct _etext location; clean up .ld files
...
1. Make _extext and _sidata coincide. Old _etext location did not include
.ARM.exidx sections, which were usually absent but not always. So flash
data was copied to RAM in wrong place.
2. Use decimal constants with "K" and "M" suffixes in .ld files instead
of hex constants, to make them easier to read and check for accuracy.
