i3c: mipi-i3c-hci: Add a quirk to set Response buffer threshold


The current driver sets the response buffer threshold value to 1
(N+1, 2 DWORDS) in the QUEUE THRESHOLD register. However, the AMD
I3C controller only generates interrupts when the response buffer
threshold value is set to 0 (1 DWORD).

Therefore, a quirk is added to set the response buffer threshold value
to 0.
