[PATCH i-g-t 0/2] Add a check for power management PCI capability

[Jakub Kolakowski]

This patch series is introducing a helper for checking the presence of
power management PCI capability and it utilizes this new helper in
xe_pm tests that are related to D-states.

Add power management capability checking helper. With this helper one
can make sure the capability is present on device under test before
proceeding with any actions related to PM. This is mainly aimed to check
for availability of D-states but overall it checks for the PCI
capability in general.

Add a check for power management capability of device tested in tests
related to D-states. Currently if test is started on configuration
that does not support the PM capability it doesn't skip, instead
depending on test it may fail, abort or timeout.
With this change test will skip with a clear message why it did.
