As the PolarFire SoC needs SGMII to connect the PHY, check the
'phy-mode' property of device tree node for ethernet and act on it
appropriately.
Add the compatible strings for the PolarFire SoC device tree.
'microchip,mpfs-mss-gem" is not officially documented but has been
observed in the available firmware for this platform, so it is included
for now.
Also, fix a typo in if_cgem_hw.h.

Rather than doing these checks based on the detected hardware variant, allow
quirks to be specified as a set of flags for each compatible string.
This simplifies adding support for new compatible hardware.

Note that currently Linux's device tree uses the FU540's compatible
string, as does upstream U-Boot, but the U-Boot shipped with the board
based on an older patch series has the correct FU740 name. Thankfully
they are the same, at least as far as software is concerned.
Whilst here, fix a style(9) nit.

BUS_DMA_NOCACHE should only be used when one needs to guarantee the
created mapping has uncached memory attributes, usually as a result
of buggy hardware. Normal use cases should pass BUS_DMA_COHERENT, to
create an appropriate mapping based on the flags passed to
bus_dma_tag_create().
This should have no functional change, since the DMA tags in this driver
are created without the BUS_DMA_COHERENT flag.

The cgem(4) driver was updated to support 64-bit bus addressing in
facdd1cd20. However, the committed version determines this in an
un-idiomatic way. Change the compile-time conditional to check
BUS_SPACE_MAXADDR, rather than comparing int and pointer sizes.

This is mostly indentation whitespace, and reflowing a few multiline
comments. This gets a bunch of minor stuff out of the way so that the diffs
for style don't clutter up the diffs for some upcoming functional changes.

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.
This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.
Mark all obvious cases as MPSAFE. All entries that haven't been marked
as MPSAFE before are by default marked as NEEDGIANT

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

that it can connect to switches at speeds other than 1gb.
This requires changing the reference clock speed. Since we still don't
have a general clock API that lets a SoC-independant driver manipulate its
own clocks, this change includes a weak reference to a routine named
cgem_set_ref_clk(). The default implementation is a no-op; SoC-specific
code can provide an implementation that actually changes the speed.

- Add missing calls to bus_dmamap_unload() in et(4).
- Check the bus address against 0 to decide when to call
bus_dmamap_unload() instead of comparing the bus_dma map against NULL.
- Check the virtual address against NULL to decide when to call
bus_dmamem_free() instead of comparing the bus_dma map against NULL.
- Don't clear bus_dma map pointers to NULL for static allocations.
Instead, treat the value as completely opaque.
- Pass the correct virtual address to bus_dmamem_free() in wpi(4) instead
of trying to free a pointer to the virtual address.
