Karol Kolacinski 6e8b2c88fc ice: handle extts in the miscellaneous interrupt thread 
The ice_ptp_extts_work() and ice_ptp_periodic_work() functions are both
scheduled on the same kthread worker, pf.ptp.kworker. The
ice_ptp_periodic_work() function sends to the firmware to interact with the
PHY, and must block to wait for responses.

This can cause delay in responding to the PFINT_OICR_TSYN_EVNT interrupt
cause, ultimately resulting in disruption to processing an input signal of
the frequency is high enough. In our testing, even 100 Hz signals get
disrupted.

Fix this by instead processing the signal inside the miscellaneous
interrupt thread prior to handling Tx timestamps.

Use atomic bits in a new pf->misc_thread bitmap in order to safely
communicate which tasks require processing within the
ice_misc_intr_thread_fn(). This ensures the communication of desired tasks
from the ice_misc_intr() are correctly processed without racing even in the
event that the interrupt triggers again before the thread function exits.
