Subject: [PATCH net-next v6 2/5] net: ti: icssg-prueth: Stop hardcoding def_inc

The def_inc is stored in icss_iep structure. Currently default increment
(ns per clock tick) is hardcoded to 4 (Clock frequency being 250 MHz).
Change this to use the iep->def_inc variable as the iep structure is now
accessible to the driver files.
