Details

Summary

These functions are needed for building drm5.2. They should not
introduce any known backwards compatability issues.

pci_dev_present shows if a set of pci ids are present in the system.
It just wraps pci_find_device.

synchronize_srcu_expedited likewise wraps the existing synchronize_src
lkpi function.

Test Plan

Tested with drm5.2 wip on Intel UHD 605.

Sorry my style habits are taking a little while to form.

I'll make a new review for the srcu changes in a moment.
