net: micrel: Fix KS8851 Kconfig

Browse Source 
KS8851 selects MICREL_PHY, which depends on PTP_1588_CLOCK_OPTIONAL, so
make KS8851 also depend on PTP_1588_CLOCK_OPTIONAL.

Fixes kconfig warning and build errors:

WARNING: unmet direct dependencies detected for MICREL_PHY
  Depends on [m]: NETDEVICES [=y] && PHYLIB [=y] && PTP_1588_CLOCK_OPTIONAL [=m]
    Selected by [y]:
