ixgbe: fix timer support for X550em

An issue is found on x550em NICs: ieee1588 is not working, the time is
always reported as 0.
The root cause is that the timer is only supported by the driver for x550,
switch statement entries are missing for x550em_x and x550em_a. This patch
adds those missing entries.

Fixes: a7740dc1303a ("ixgbe: support new devices and MAC types")
