Currently, it's possible to pass various attributes to an IOMMU's
<driver/> element hoping that we enable them in underlying
hypervisor. However, depending on the IOMMU model, some of these
attributes can't be enabled and are simply ignored. This is
suboptimal and we should reject such configuration in the
validate phase.

In most cases, disabling the secure-boot or the enrolled-keys

It should be enough to enable or disable the enrolled-keys feature
to control whether Secure Boot is enforced, but there's a slight
complication: many distro packages for edk2 include, in addition
to general purpose firmware images, builds that are targeting the
Confidential Computing use case.
For those, the firmware descriptor will not advertise the
enrolled-keys feature, which will technically make them suitable
for satisfying a configuration such as
<os firmware='efi'>
<firmware>
<feature state='off' name='enrolled-keys'/>
</firmware>
</os>
In practice, users will expect the general purpose build to be
used in this case. Explicitly asking for the secure-boot feature
to be enabled achieves that result at the cost of some slight
additional verbosity.

pretend only TPM-1.2 is available, QEMU-6.* has both TPM-1.2 and

thus domaincapstest calls the real implementation, which tries to
execute swtpm_setup binary. This fails, because
virFindFileInPath() is mocked in such way that it returns NULL

should mock the function which tries to execute it so that
predictable result is returned.
