Bluetooth: Add quirk to disable MWS Transport Configuration
Broadcom 4378/4387 controllers found in Apple Silicon Macs claim to
support getting MWS Transport Layer Configuration,
< HCI Command: Read Local Supported... (0x04|0x0002) plen 0
> HCI Event: Command Complete (0x0e) plen 68
Read Local Supported Commands (0x04|0x0002) ncmd 1
Status: Success (0x00)
[...]
Get MWS Transport Layer Configuration (Octet 30 - Bit 3)]
[...]
, but then don't actually allow the required command:
> HCI Event: Command Complete (0x0e) plen 15
Get MWS Transport Layer Configuration (0x05|0x000c) ncmd 1
Status: Command Disallowed (0x0c)
Number of transports: 0
Baud rate list: 0 entries
