The beagleboard TI kernel 4.14 and 4.19 contain a commit which change
the device names ("pwm: Create device class for pwm channels") from
pwmN to pwm-${chip}:N. This commit was never merged into the upstream
kernel.
Decrease the number of pwm channels to a more reasonable 16. Increase
the number of pwm chips to 8 since the replicape servo pwm outputs are
on pwmchip4.
Update replicape code to detect appropriate channel.
