HAD is a mandatory features with SMMUv3.1 if S1P is set, which is
our case. Other 3.1 mandatory features come with S2P which we don't
have.
So let's support HAD and advertise SMMUv3.1 support in AIDR.
HAD support allows the CD to disable hierarchical attributes, ie.
if the HAD0/1 bit is set, the APTable field of table descriptors
walked through TTB0/1 is ignored.

Enhance the smmu_iotlb_inv_iova() helper with range invalidation.
This uses the new fields passed in the NH_VA and NH_VAA commands:
the size of the range, the level and the granule.
As NH_VA and NH_VAA both use those fields, their decoding and
handling is factorized in a new smmuv3_s1_range_inval() helper.

The bit offsets in the EVT_SET_ADDR2 macro do not match those specified
in the ARM SMMUv3 Architecture Specification. In all events that use
this macro, e.g. F_WALK_EABT, the faulting fetch address or IPA actually
occupies the 32-bit words 6 and 7 in the event record contiguously, with
the upper and lower unused bits clear due to alignment or maximum
supported address bits. How many bits are clear depends on the
individual event type.
Update the macro to write to the correct words in the event record so
that guest drivers can obtain accurate address information on events.

An IOVA/ASID invalidation is notified to all IOMMU Memory Regions
through smmuv3_inv_notifiers_iova/smmuv3_notify_iova.
When the notification occurs it is possible that some of the
PCIe devices associated to the notified regions do not have a
valid stream table entry. In that case we output a LOG_GUEST_ERROR
message, for example:
invalid sid=<SID> (L1STD span=0)
"smmuv3_notify_iova error decoding the configuration for iommu mr=<MR>
This is unfortunate as the user gets the impression that there
are some translation decoding errors whereas there are not.
This patch adds a new field in SMMUEventInfo that tells whether
the detection of an invalid STE must lead to an error report.
invalid_ste_allowed is set before doing the invalidations and
kept unset on actual translation.
The other configuration decoding error messages are kept since if the
STE is valid then the rest of the config must be correct.

Header guard symbols should match their file name to make guard

[Rebase to master: update include/hw/net/ne2000-isa.h]
In case the STE's config is "Bypass" we currently don't set the
IOMMUTLBEntry perm flags and the access does not succeed. Also
if the config is 0b0xx (Aborted/Reserved), decode_ste and
smmuv3_decode_config currently returns -EINVAL and we don't enter
the expected code path: we record an event whereas we should not.
This patch fixes those bugs and simplifies the error handling.
decode_ste and smmuv3_decode_config now return 0 if aborted or
bypassed config was found. Only bad config info produces negative
error values. In smmuv3_translate we more clearly differentiate
errors, bypass/smmu disabled, aborted and success cases. Also
trace points are differentiated.
