net: fec: do not allow enabling PPS and PEROUT simultaneously

Browse source

[ Upstream commit c0a1f3d7e1 ]

In the current driver, PPS and PEROUT use the same channel to generate
the events, so they cannot be enabled at the same time. Otherwise, the
later configuration will overwrite the earlier configuration. Therefore,
when configuring PPS, the driver will check whether PEROUT is enabled.
Similarly, when configuring PEROUT, the driver will check whether PPS
is enabled.
