[Intel-xe] [PATCH v2] drm/xe: clear the serviced bits on INTR_IDENTITY_REG

[Intel-xe] [PATCH v2] drm/xe: clear the serviced bits on INTR_IDENTITY_REG

[Jonathan Cavitt]

The spec for this register, like many other interrupt related ones,
asks software to write back '1' to clear the serviced bits. Let's
respect the spec.

v2:
- Update commit message
- Add missing CC

Please rebase it, but feel free to keep the rv-b.
