The NETWORK_PHY_TIMESTAMPING configuration option adds overhead into
the networking stack.  When enabled, all transmitted and received
frames are subjected to extra tests to determine whether they just
might be PTP frames to be presented to esoteric PHY time stamping
drivers.

However, no System on Chip, least ways not the axm55xx SoC, includes
such a PHY time stamping device.  Disable the unneeded option by
default.
