Implement kref backed reference counting instead of rolling our own. This
elimnates the need of the following fields in 'struct fc_bsg_job':

Export fc_bsg_jobdone so drivers can use it directly instead of doing
the round-trip via struct fc_bsg_job::job_done() and use it in the LLDDs.
As we've converted all LLDDs over to use fc_bsg_jobdone() directly,
we can remove the function pointer from struct fc_bsg_job as well.

struct fc_bsg_buffer is just a clone of struct bsg_buffer from bsg-lib,
so use this one instead.

You can call irq_enter/exit() in __smp_reschedule_interrupt(). It can be
called nested.
Thanks,
Introduce a new DOMAIN_ATTR_MSI_RESV domain attribute and associated
iommu_domain msi_resv field. It comprises the size and alignment
of the IOVA reserved window dedicated to MSI mapping. This attribute
only is supported when MSI must be IOMMU mapped.
This is the case on ARM.

We introduce the capability to (un)register MSI doorbells.
A doorbell region is characterized by its physical address base, size,
and whether it its safe (ie. it implements IRQ remapping). A doorbell

From: Robin Murphy
IOMMU domain users such as VFIO face a similar problem to DMA API ops
with regard to mapping MSI messages in systems where the MSI write is
subject to IOMMU translation. With the relevant infrastructure now in
place for managed DMA domains, it's actually really simple for other
ARM smmu and smmu-v3 translate MSI transactions so their driver
are must implement domain_get_attr for DOMAIN_ATTR_MSI_RESV.
This allows to retrieve the size and alignment requirements of
the MSI reserved IOVA window.
Also IOMMU_DMA gets selected since it exposes the API to map the
MSIs.
