[PATCH] net: ti: icssg-prueth: add PTP_1588_CLOCK_OPTIONAL dependency

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

The new icssg-prueth driver needs the same dependency as the other parts
that use the ptp-1588:

WARNING: unmet direct dependencies detected for TI_ICSS_IEP
  Depends on [m]: NETDEVICES [=y] && ETHERNET [=y] && NET_VENDOR_TI [=y] && PTP_1588_CLOCK_OPTIONAL [=m] && TI_PRUSS [=y]
  Selected by [y]:
  - TI_PRUETH [=y] && NETDEVICES [=y] && ETHERNET [=y] && NET_VENDOR_TI [=y] && PRU_REMOTEPROC [=y] && NET_SWITCHDEV [=y]

Add the correct dependency on the two drivers missing it, and remove
the pointless 'imply' in the process.

Fixes: e654b85a693e ("net: ti: icssg-prueth: Add ICSSG Ethernet driver for AM65x SR1.0 platforms")
Fixes: 511f6c1ae093 ("net: ti: icssm-prueth: Adds ICSSM Ethernet driver")
