net: ti: icss-iep: fix setting counter value

[ Upstream commit 83b9dda8afa4e968d9cce253f390b01c0612a2a5 ]

Currently icss_iep_set_counter() writes the upper 32-bits of the
counter value to both the lower and upper counter registers, so
fix this by writing the appropriate value to the lower register.
