This patch adds the missing pieces needed for device setup using the
mlx5en driver inside a virtual machine which is providing hardware
access through SR-IOV.

- Validate the scheduling class against the actual limit (which is chip
specific) instead of a magic number.
- Return an error if an attempt is made to manipulate the tx queues of a
VI that hasn't been initialized.

The SYSINIT runs at SI_SUB_KICK_SCHEDULER after the scheduler is fully
initialized and timers are working. This fixes booting in the
EARLY_AP_STARTUP case.
A couple of mostly cosmetic fixes for the final initialization of netfront:
- Switch to "connected" state before starting to kick the rings.
- Correctly use "rxq" in the initialization loop (previously rxq was not
updated in the loop, and netfront would kick np->rxq[N] several times).
- Declare and define xn_connect as static, it's not used outside of this
file.

COMPAT_ARCH32 does not seem to have existed. Also remove some
leftovers from the sysent rework in r301404. Include

This trips me up whenever I'm fooling around with partially supported
NICs that fail to fully attach or initialise - the firmware gets loaded
and references, but something fails - and the firmware references
aren't cleaned up.
After perusing the PHY-LP code (don't ask why; honest) I discovered that
it /has/ 5GHz support - but it's not ever used. I found one NIC - a
BCM4312 w/ pci id 0x4315 - which advertised dual-band PHY-LP support.
Turns out it works.
Whilst here, move up the support bit logging code so I can use it
to debug this.
Tested:
* BCM4312 (pci id 0x4315); 5GHz STA operation
On Medford, licenses are required to enable RX and event cut through and to
disable RX batching. To avoid the need for the driver to make decisions based on
the licensing state, the MC_CMD_INIT_EVQ has been extended to allow us to leave
the decision to the firmware. If the adapter is licensed for low-latency use,
the firmware will choose the optimal settings for latency, otherwise it will use
the best settings for throughput.
For Huntington we still need to choose the settings ourselves.

Add support for fetching SPROM data from OTP on chipsets with an
IPX OTP controller (including the BCM43225).
This integrates the NVRAM data source into the chipc_caps capability
structure, and adds a sprom_offset field that can be used with OTP
to locate the SPROM image data (found within the general use
region, H/W subregion).
This also removes one of two duplicate parse error messages reported by
both the bhnd_sprom driver and the underlying SPROM parsing API.

Now that bhnd(4) provides feature parity with the previous siba/mips
implementation, we can switch sentry5 over and begin lifting common
support code out for use across bhnd(4) embedded targets.
Changes:
- Fixed enumeration of siba(4) per-core address maps, required for
discovery of memory mapped chipc flash region on siba(4) devices.
- Simplified bhnd kernel configuration (dropped 'bhndbus' option).
- Replaced files.broadcom's direct file references with their
corresponding standard kernel options.
- Lifted out common bcma/siba nexus support, inheriting from the new
generic bhnd_nexus driver.
- Dropped now-unused sentry5 siba code.
- Re-integrated BCM into the universe build now that it actually compiles.

When the low-latency firmware variant is running, it is reported as not
being capable of batching RX events, but it can still do so if the
FORCE_EV_MERGING flag is set on an RXQ. Therefore we need to handle
batched RX events even if the capability isn't set.
If this bug is fixed in the firmware such that the capability is set
even when running the low-latency firmware variant, it will almost
always be reported so I don't think we lose much by removing the check.

BAR size to 1MB. According to Xeon v3 specifications and my tests, that
size register is write-once and so not writeable after BIOS written it.
Instead of that, make the code work with BAR of any sufficient size,
properly calculating offset within its base. It also simplifies the code.
