Janne Grunau 478a916f51 replicape: add support for Linux hardware PWM (#1443) ...

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.
