Bluetooth: btbcm: Support pcm configuration
Add BCM vendor specific command to configure PCM parameters. The new
vendor opcode allows us to set the sco routing, the pcm interface rate,
and a few other pcm specific options (frame sync, sync mode, and clock
mode). See broadcom-bluetooth.txt in Documentation for more information
about valid values for those settings.
Here is an example trace where this opcode was used to configure
a BCM4354:
< HCI Command: Vendor (0x3f|0x001c) plen 5
01 02 00 01 01
> HCI Event: Command Complete (0x0e) plen 4
Vendor (0x3f|0x001c) ncmd 1
Status: Success (0x00)
We can read back the values as well with ocf 0x001d to confirm the
values that were set:
$ hcitool cmd 0x3f 0x001d
< HCI Command: ogf 0x3f, ocf 0x001d, plen 0
> HCI Event: 0x0e plen 9
01 1D FC 00 01 02 00 01 01
