Added linux host MCU board pin aliases for endstops.
Also added a sample filament switch sensor config.

The servo pins (P9_14/P9_16) are muxed to the SOCs hardware PWM unit
driven by a 13MHz GP timer. They have to be driven by the linux host
mcu. This commits adds hardware PWM support using the linux sysfs
user space interface.
The servo pins can be specified as "replicape:servo0" and
"replicape:servo1". Removes the "servo0_enable", "servo1_enable"
configuration parameters.
Fixes#1105.

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 enable lines are not one per stepper - instead there are 5
distinct enable settings. Handle them properly.

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.
