net: ti: icss-iep: Reject perout generation request
IEP driver supports both perout and pps signal generation
but perout feature is faulty with half-cooked support
due to some missing configuration. Remove perout
support from the driver and reject perout requests with
"not supported" error code.
Fixes: c1e0230eeaab2 ("net: ti: icss-iep: Add IEP driver")
