Heiko Thiery 4a104e4d4d net: fec: ptp: avoid register access when ipg clock is disabled
[ Upstream commit 6a4d7234ae ]

When accessing the timecounter register on an i.MX8MQ the kernel hangs.
This is only the case when the interface is down. This can be reproduced
by reading with 'phc_ctrl eth0 get'.

Like described in the change in 91c0d987a9
the igp clock is disabled when the interface is down and leads to a
system hang.

So we check if the ptp clock status before reading the timecounter
register.
