[PATCH v2] dpaa2-ptp: fix compile error

[Chen Wandun <chenwandun@huawei.com>]

From: Chenwandun <chenwandun@huawei.com>

phylink_set_port_modes will be compiled if CONFIG_PHYLINK enabled,
dpaa2_mac_validate will be compiled if CONFIG_FSL_DPAA2_ETH enabled,
it should select CONFIG_PHYLINK when dpaa2_mac_validate call
phylink_set_port_modes

drivers/net/ethernet/freescale/dpaa2/dpaa2-mac.o: In function `dpaa2_mac_validate':
