Certain use cases require performance that can't be achieved with the
general-purpose SMMU page table code. By limiting ourselves to 4K page
mappings (no block mappings) and pre-populating the first and second
levels of the page tables up front, we can eliminate a lot of the work
needed for page table mapping and unmapping.
Add a performance-tuned io-pgtable implementation for ARMv8L page tables
that only supports 4K page mappings. Any size can be mapped, but only
4K page mappings will be installed in the page tables.

Currently we restrict the pgsize_bitmap for the entire SMMU every time
we allocate some new page tables. However, certain io-pgtable
implementations might wish to restrict the formats beyond the
restrictions of the SMMU itself, which forces all domains on that SMMU
to the same pgsize_bitmap, even if the other domains would prefer to use
a more permissive page table format. Besides that, some SMMUs in the
system might have different supported page sizes at the hardware level,
so applying those to everyone else is wrong.
Fix these issues by implementing the new .get_pgsize_bitmap IOMMU op.

Currently we use a single pgsize_bitmap per IOMMU driver. However, some
IOMMU drivers might service different IOMMUs with different supported
page sizes. Some drivers might also want to restrict page sizes for
different use cases. Support these use cases by adding a
.get_pgsize_bitmap function to the iommu_ops which can optionally be
used by the driver to return a domain-specific pgsize_bitmap.

Most of CPUs increase cycle counter by one every cycle which makes
frequency = cycles / time_delta is correct. Therefore it's reasonable
to get rid of current cpu_cycle_max_scale_factor and ask cycle counter
read callback function to return scaled counter value when it's needed
in such a case that cycle counter doesn't increase every cycle.
Thus multiply NSEC_PER_SEC / HZ_PER_KHZ to CPU cycle counter delta
as we calculate frequency in khz and remove cpu_cycle_max_scale_factor.
This allows us to simplify frequency estimation and cycle counter API.

USB GSI function driver uses usb_ipa_w work to queue different events
like EVT_CONNECTED, EVT_DISCONNECTED and more. ipa_event_handler()
uses those events as inputs to make necessary decision about performing
connect and disconnect with IPA driver. It is required that before USB
GSI driver calls ipa_usb_deinit_teth_prot(), it has invoked IPA
disconnect API ipa_usb_xdci_disconnect() if it has called
ipa_usb_xdci_connect() API. Current code is making sure that any
running usb_ipa_w work is being completed before calling
ipa_usb_deinit_teth_prot() but if work is not scheduled and pending,
ipa_usb_xdci_connect() is not called (i.e. later when usb_ipw_w work is
scheduled, EVT_DISCONNECTED is being processed but gsi_unbind() has
changed sm_state as STATE_UNINITIALIZED which results into no-ops.)
which results into USB and IPA driver go out of sync in terms of
expected state machine. Hence calling ipa_usb_init_teth_prot() on next
USB cable connect from gsi_bind_config() fails which results into no
USB GSI functionality. Fix this issue by using drain_workqueue() instead
of flush_workqueue() which makes sure that re-queue work is flushed.
