PCI: Mark TI C667X to avoid bus reset

stable inclusion
from stable-5.10.46
commit 1e460ddf5be1dae1f2b4c46b5a16b0f32bec4e1d
bugzilla: 168323
CVE: NA

--------------------------------

commit b5cf198e upstream.

Some TI KeyStone C667X devices do not support bus/hot reset.  The PCIESS
automatically disables LTSSM when Secondary Bus Reset is received and
device stops working.  Prevent bus reset for these devices.  With this
change, the device can be assigned to VMs with VFIO, but it will leak state
between VMs.
