5423e4966c rp2pio: Transfer up to 32 bytes before checking background tasks 
@Jerryneedell noticed that this problem affected strips short enough
to not use the DMA peripheral, thanks for the hot tip!

Instead of checking for background tasks after every byte transfer,
try up to 32 transfers before attending to background tasks.

This fixes the problem I was seeing on my 5-pixel circuit.

Closes #4135.

Add SMPS mode pin to Raspi Pico pins.c 
Add SMPS mode pin to Raspi Pico pins.c; see section "4.3. Using the ADC" of the Pico datasheet for discussion. 

Driving this pin high forces the onboard regulator into a lower noise PWM mode.

6e153d9948 raspberrypi: implement reset, reset_to_bootloader 
This makes all the following work:
 * normal microcontroller.reset()
 * reset into safe mode or UF2 bootloader via microcontroller.on_next_reset()
 * reset into UF2 bootloader via the "1200 baud trick"

The implementation of reset_cpu is from micropython.

Add initial RP2040 support 
The RP2040 is new microcontroller from Raspberry Pi that features
two Cortex M0s and eight PIO state machines that are good for
crunching lots of data. It has 264k RAM and a built in UF2
bootloader too.
