habanalabs/gaudi: remove PCI access to SM block
Due to HW limitation we must remove all direct access to SM registers, in order to do that we will access SM registers using the HW QMANS. When possible and no user context is present, we can directly access the HW QMANS. Whenever there is an active user, driver will prepare a pending command buffer list which will be sent upon user submissions.
