[ Upstream commit 91b6d02ddcd113352bdd895990b252065c596de7 ]
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)
