[PATCH net-next] liquidio: remove PTP support in 23XX adapters

[Felix Manlunas]

From: Prasad Kanneganti <prasad.kannega...@cavium.com>

liquidio driver incorrectly indicates that PTP is supported in 23XX
adapters; this patch fixes that.  PTP is supported in 66XX and 68XX
adapters, and the driver correctly indicates that.
