During the review of 09cdf4878c we
switched from cached registers to reading them as needed.
One read of the two reads was moved after the softreset got triggered
and as a result returned 0 rather than the proper register value.
Moving the read before the softreset gets initiated seems to make
things work again and xhci.c no longer complains about
"Controller does not support 4K page size.".

The two implementations for the pca9548 switch and the pca9547 mux
seemed close enough so we can put them together and with a bit more
abstraction add pca9540 support.
While here apply a bit of consistency in variable and driver naming and
use device_has_property instead of the FDT-only OF_ variant.
This disconnects pca9547 from the build but does not yet delete it.

When accessing a register directly from etherswitchcfg one must specify
a register group(e.g. registers of portN) and the register offset within
the group. The latter is passed as the 5 least significant bits.
Extract the former by dividing the register address by 32, not by 5.

Rather than hiding behind #if 0, hide the debugging behind DWC3_DEBUG

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.

During probe the driver created a temporary buffer to which the value of
DEVICE_DESC constant was printed. This buffer was then copied to the
device structure using device_set_desc_copy. Since the value of this
string is exactly the same for every device using the ENA driver, using
sprintf is unnecessary, and device_set_desc can be used instead.

Copying ENI metrics was done in callout context, this caused the driver
to panic when sample_interval was set to a value other than 0, as the
admin queue call which was executed could sleep while waiting on
a condition variable. Taskqueue, unlike callout, allows for sleeping, so
moving the function to a separate taskqueue fixes the problem.
ena_timer_service is still responsible for scheduling the taskqueue.
Stop draining the callout during ena_up/ena_down. This was done to
prevent a race between ena_up/down and ena_copy_eni_metrics admin queue
calls. Since ena_metrics_task is protected by ENA_LOCK there is no
possibility of a race between ena_up/down and ena_metrics_task.
Remove a comment about locking in ena_timer_service. With ENI metrics
in a separate task this comment became obsolete.

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
