The PRU code size has grown too close to the maximum - remove the ADC
code to reduce its overall size. (On the beaglebone, the Linux
process can, and typically does, do the ADC reading.)

Don't use tiny step distances on the Z as that could cause a surprise
to users that copy the config without updating all the settings. (A Z
step distance that is too small would cause a high motor velocity.) A
step distance of .0025 is very popular in practice, so change the
default example configs to use that.

The Beaglebone hardware prevents the PRU from updating the pinmux
board settings. As a result, the PRU can't directly change the pin
direction or change the pullup resistor settings. Warn the Beaglebone
users of this limitation.
