Bluetooth: Add quirk to disable extended scanning
Broadcom 4377 controllers found in Apple x86 Macs with the T2 chip
claim to support extended scanning when querying supported states,
< HCI Command: LE Read Supported St.. (0x08|0x001c) plen 0
> HCI Event: Command Complete (0x0e) plen 12
LE Read Supported States (0x08|0x001c) ncmd 1
Status: Success (0x00)
States: 0x000003ffffffffff
[...]
LE Set Extended Scan Parameters (Octet 37 - Bit 5)
LE Set Extended Scan Enable (Octet 37 - Bit 6)
[...]
, but then fail to actually implement the extended scanning:
< HCI Command: LE Set Extended Sca.. (0x08|0x0041) plen 8
Own address type: Random (0x01)
Filter policy: Accept all advertisement (0x00)
PHYs: 0x01
Entry 0: LE 1M
Type: Active (0x01)
Interval: 11.250 msec (0x0012)
Window: 11.250 msec (0x0012)
> HCI Event: Command Complete (0x0e) plen 4
LE Set Extended Scan Parameters (0x08|0x0041) ncmd 1
Status: Unknown HCI Command (0x01)
