Unfortunately 5720S uses 5709S PHY id so add a hack to detect 5720S
PHY by checking parent device name. 5720S PHY does not support 2500SX.

We also try to make better use of the fs flags instead of
trying adapt the code according to the fs structures. In
the case of subsecond timestamps and birthtime we now
check that the feature is explicitly enabled: previously
we only checked that the reserved space was available and
silently wrote them.
This approach is much safer, especially if the filesystem
happens to use embedded inodes or support EAs.

- Use the new architecture-agnostic buffer pool manager that uses uma(9)
to manage a set of power-of-2 sized buffers for bus_dmamem_alloc().
- Create pools of buffers backed by both regular and uncacheable memory,
and use them to handle regular versus BUS_DMA_COHERENT allocations.
- Use uma(9) to manage a pool of bus_dmamap structs instead of local code
to manage a static list of 500 items (it took 3300 maps to get to
multi-user mode, so the static pool wasn't much of an optimization).
- Small BUS_DMA_COHERENT allocations no longer waste an entire page per
allocation, or set pages to uncached when they contain data other than
DMA buffers. There's no longer a need for drivers to work around the
inefficiency by allocing large buffers then sub-dividing them.
- Because we know the alignment and padding of buffers allocated by
bus_dmamem_alloc() (whether coherent or regular memory, and whether
obtained from the pool allocator or directly from the kernel) we
can avoid doing partial cacheline flushes on them.
- Add a fast-out to _bus_dma_could_bounce() (and some comments about
what the routine really does because the old misplaced comment was wrong).
- Everywhere the dma tag alignment is used, the interpretation is that
an alignment of 1 means no special alignment. If the tag is created
with an alignment argument of zero, store it in the tag as one, and
remove all the code scattered around that changed 0->1 at point of use.
- Remove stack-allocated arrays of segments, use a local array of two
segments within the tag struct, or dynamically allocate an array at first
use if nsegments > 2. On an arm system I tested, only 5 of 97 tags used
more than two segments. On my x86 desktop it was only 7 of 111 tags.

manage a set of power-of-2 sized buffers for bus_dmamem_alloc().
This allows the caller to provide the back-end allocator uma allocator,
allowing full control of the memory pages backing the pool. For
convenience, it provides an optional builtin allocator that provides pages
allocated with the VM_MEMATTR_UNCACHEABLE attribute, for managing pools of
DMA buffers for BUS_DMA_COHERENT or BUS_DMA_NOCACHE.
This also allows the caller to specify a minimum alignment, and it ensures
that all buffers start on a boundary and have a length that's a multiple of
that value, to avoid using buffers that trigger partial cache line flushes.

This simplifies the code and closes few races, especially in %I handling.

Starting with firmware v7.5, the "Read TouchPad Modes" ($01) and "Read

carry variable information.
We now compare those bytes to expected constants only for firmware prior
