During media selection through ifconfig one might not specify
the duplex setting through the mediaopt flag.
In that case the igc driver would default to full-duplex.
The problem with this approach is that e1000(em/igb) driver
defaults to half-duplex.
Because of that if one connects both NICs and sets media to
e.g. 100baseTX on both of them no link will be found.
Fix that by matching igc behaviour with what e1000 does.

Split the current FDT-only implementation up into an FDT and an
ACPI part reusing and sharing as much code as possible (thanks mw!).
This makes the Synopsis XHCI root hubs attach correctly on SolidRun's
HoenyComb instead of just the generic XHCI root and this means we
are also doing proper chip setup and applying the quirk needed there [1].
There is one problem with ACPI attachment in that it uses the generic
XHCI PNP ID. So we need to do extra checks in order to not claim
all xhci, which means we check for a known quirk to be present
in acpi_probe. Long term this isn't scaling and this was discussed
in SolidRun's Discord Channel in 2021 with the intend that "jnettlet"
will take this to a steering committee. Since then ACPI has kind-of
become a technology non grata (due to not getting changes into Linux
timely) so it is unclear if this will ever happen. If there will be
further hardware with dwc3/ACPI we should go and make sure this problem
gets solved.

acpi_find_dsd() is not a bus function and we only need the acpi_device (ad).
The only caller has already looked up the ad (from ivars) for us.
Directly pass the ad to acpi_find_dsd() instead of bus, dev and remove
the extra call to device_get_ivars(); the changed argument also means we
now call AcpiEvaluateObject directly on the handle.
This optimisation was done a while ago while debugging a driver which
