acpicpu.c
Fix the hw.cpuspeed implementation and make sure frequency calculations don't end up triggering a divide by zero.

acpiiort.c
On the Lenovo X13s the named components don't have the single mapping flag set, which we so far had expected to be there. This is allowed by the IORT spec. In that case simply make use of the first mapping if there is a single one.

acpiiort.h
While it seems like we can choose any I/O virtual address for peripheral devices, this isn't really the case. It depends on the bus topology of how devices are connected. In the case of PCIe, devices are assigned addresses (in PCI BARs) from the PCI address spaces. Now if we take an address from one of these address spaces for our IOVA, transfers from from a PCI device to that address will terminate inside of the PCI bus. This is because from the PCI buses' point-of-view, the address we chose is part of its address space. To make sure we don't allocate addresses from there, reserve the PCI addresses in the IOVA.

acpipci.c
Advertise MSI multiple-vector support. This is assuming that in ACPI mode we probably have a GIC with MSI support that should give us have plenty of MSI vectors for us to use. Improves qwz(4) behavior on the Orion O6.

aplcpu.c
Apparently we can't have "generic" compatibles anymore, even though they were accepted when support for the M1 and M1 Pro chips was upstreamed. So now we have an incoherent mess where we need to add the right SoC-specific compatble to the list of compatibles to make sure drivers still attach when we update device trees to the latest Linux versions.

aplmca.h
Add aplaudio(4) and aplmca(4). The aplmca(4) driver controls the hardware block that takes data from apldma(4), serializes it and sends it out on the i2s ports. The aplaudio(4) driver ties together aplmca(4) and various codecs to present an audio(4) interface to the system.

The device tree bindings changed during the upstreaming process. Since it is relatively easy to support both the old and the new, do so.

smmu.c
Request 64k-aligned IOVA blocks. It's a bit unfortunate the alignment requirements only diffuse through to the bus dma API when we allocate memory; at that point we already have IOVA allocated, so it's hard to apply the right alignment. The good thing is that we basically cannot run out of an IOMMU domain's IOVA (which for us is per device), so we can easily bump the alignment of each DMA map. This helps qwz(4) FW come up on the Orion O6.
