Eliminate 1 XX_VirtToPhys() and 2 XX_PhysToVirt() calls from if_dtsec(4)

XX_VirtToPhys(), by way of pmap_kextract(), is an expensive operation.
Profiling via dtrace during a series of iperf tests I found 16111 / 30432
stack frames were located in mmu_booke_kextract(), so eliminating this
expensive call should improve performance slightly. XX_PhysToVirt() is not
as expensive, but redundant calls in this context is wasteful.

Make DPAA work in 64-bit mode

Rework the dTSEC and FMan drivers to be more like a full bus relationship,
so that dtsec can use bus_alloc_resource() instead of trying to handle the
offset from the dts. This required taking some code from the sparc64 ebus
driver to allow subdividing the fman region for the dTSEC devices.

Update DPAA SDK to SDK 2.0

This adds some support for ARM as well as 64-bit. 64-bit on PowerPC is
currently not working, and ARM support has not been completed or tested on the
FreeBSD side.

As this was imported from a Linux tree, it includes some Linux-isms
(ioread/iowrite), so compile with the LinuxKPI for now. This may change in the
future.

Shorten list of arguments to mbuf external storage freeing function.

All of these arguments are stored in m_ext, so there is no reason
to pass them in the argument list. Not all functions need the second
argument, some don't even need the first one. The second argument
lives in next cache line, so not dereferencing it is a performance
gain. This was discovered in sendfile(2), which will be covered by
next commits.

The second goal of this commit is to bring even more flexibility
to m_ext mbufs, allowing to create more fields in m_ext, opaque to
the generic mbuf code, and potentially set and dereferenced by
subsystems.

Use UMA_ALIGN_PTR to specify pointer alignment

The alignment argument is the mask of low bits to mask off when allocating
items in a zone, not the block-size alignment.

Simplify the page tracking for VA<->PA translations.

Drop the tracking down to the pmap layer, with optimizations to only track
necessary pages. This should give a (slight) performance improvement, as well
as a stability improvement, as the tracking is already mostly handled by the
pmap layer.

Make dpaa work with only slightly modified Linux device trees.

Linux has a slightly different device tree definition for DPAA than originally
done in the FreeBSD driver. This changes the driver to be mostly compatible
with the Linux device tree definitions. Currently the differences are:

bman-portals: compatible = "fsl,bman-portals" (Linux is "simple-bus")
qman-portals: compatible = "fsl,qman-portals" (Linux is "simple-bus")
fman: compatible = "fsl,fman" (Linux is "simple-bus")

The Linux device tree doesn't specify anything for rgmii in the mdio. This
change still requires the device tree to specify the phy-handle, and doesn't yet
support tbi.
