net: ti: icssg-prueth: add PTP dependency

Browse Source 
The driver can now use PTP if enabled but fails to link built-in
if PTP is a loadable module:

aarch64-linux-ld: drivers/net/ethernet/ti/icssg/icss_iep.o: in function `icss_iep_get_ptp_clock_idx':
icss_iep.c:(.text+0x200): undefined reference to `ptp_clock_index'

Add the usual dependency to avoid this.
