Clock the SAMD21 much faster so it can actually convert at its max 
sample rate of 350ksps.

Also added an error check of sample rate.

Fixes #1196

Speed up zero neopixel pulses. 
SK6812 on 5v is pickier than WS2812 on 5v.

Hopefully fixes #1083.

b0e33f6a11 atmel-samd: UART: allocate rx buffer in long-lived region 
This is not strictly needed in order for #1056 to be resolved,
because the "make long-lived" machinery is unaware of this pointer.

However, as UARTs are assumed to be long-lived, this change is
beneficial because it moves the long-lived buffer into the upper
memory area with other long-lived objects, instead of remaining in
the low heap.

2fbab8067a Prevent freezing USB during high frequency PulseIn. 
We now track the last time the background task ran and bail on the
PulseIn if it starves the background work. In practice, this
happens after the numbers from pulsein are no longer accurate.

This also adjusts interrupt priorities so most are the lowest level
except for the tick and USB interrupts.

e580d22f4a Use the external crystal on SAMD21 again. 
Also, re-enable calibration storage for CircuitPlayground Express.
Tested with a 500hz PWMOut on Metro M0 with Saleae:
 * with crystal 500hz
 * with usb 500hz +- 0.1hz
 * without either 487hz += 0.1hz

SAMD51 is skipped due to DFLL errata and the fact it defaults to a
factory calibrated 48mhz that works fine for USB.
