Bluetooth: Add new quirk for broken set random RPA timeout for ATS2851

Browse Source 
The ATS2851 based controller advertises support for command "LE Set Random
Private Address Timeout" but does not actually implement it, impeding the
controller initialization.

Add the quirk HCI_QUIRK_BROKEN_SET_RPA_TIMEOUT to unblock the controller
initialization.

< HCI Command: LE Set Resolvable Private... (0x08|0x002e) plen 2
        Timeout: 900 seconds
> HCI Event: Command Status (0x0f) plen 4
      LE Set Resolvable Private Address Timeout (0x08|0x002e) ncmd 1
        Status: Unknown HCI Command (0x01)
