[PATCH 0/8] Introduce GuC Doorbells Manager

[Michal Wajdeczko]

Introduce simple GuC doorbell ID manager that will be used by the
PF driver for VFs provisioning and can later be used by submission
code once we are ready to switch from H2G based notifications to
doorbells mechanism.

As preparation steps, improve existing logging and kunit code that
is used by the new code.
