net: ti: icss-iep: Add pwidth configuration for perout signal

[ Upstream commit e5b456a14215e3c0e84844c2926861b972e03632 ]

icss_iep_perout_enable_hw() is a common function for generating
both pps and perout signals. When enabling pps, the application needs
to only pass enable/disable argument, whereas for perout it supports
different flags to configure the signal.

But icss_iep_perout_enable_hw() function is missing to hook the
configuration params passed by the app, causing perout to behave
same a pps (except being able to configure the period). As duty cycle
is also one feature which can configured for perout, incorporate this
in the function to get the expected signal.
