Initial cut at Intel AX210 bluetooth support

[shurd]

Summary

This allows loading the firmware and attaching the driver. I haven't yet managed to pair with aything.

Test Plan

Will test with BT stuff I have laying around.

[shurd]

• Add to devd

[shurd]

• Fix comment.

[shurd]

Tested with Google Pixel Buds A... with virtual_oss, pairs and right channel works.

[shurd]

• Retry reset command up to twice.

[shurd]

• Add macros for TLV types

[shurd]

• Update manpage

[shurd]

Going on vacation for a couple weeks, and will look at this again when I get back... adding adrian@ as a reviewer, feel free to add more appropriate reviewers as actionable feedback will be welcome when I return.

I wonder if that'll support a lot more than just AX210?

[shuriku_shurik.kiev.ua]

With minor modifications and updated comms/iwmbtfw it works with AX211.

I tested this change in 14.1-STABLE and a pair of Fairbuds XL. After ensuring the firmware was loaded, I ran the following commands:

1. service bluetooth start ubt0
2. hccontrol -n ubt0hci inquiry
3. hccontrol -n ubt0hci create_connection headphones
4. <added entries to /etc/bluetooth/hcsecd.conf and /etc/bluetooth/hosts>`
5. virtual_oss -T /dev/sndstat -S -a o,-4 -C 2 -c 2 -r 44100 -b 16 -s 1024 -R /dev/null -P /dev/bluetooth/headphones -d dspbt -t vdsp.ctl

I tried this both with and without running hccontrol -n ubt0hci write_authentication_enable 1, and settings the -P device name to /dev/bluetooth/headphones and /dev/bluetooth/<BT_ADDR>

With the Fairbuds, I received backend_bt: PSM=0x19 and backend_bt: Could not connect to HC: 60 after running the virtual_oss command.

I'll add markj to reviews as he was the one to add the last additions if I remember correctly and actually knows the code.
Also wulf has been active in that area in the past if I don't misremember.

Might help you to actually get a good review.
