PCI: Mark ASM1164 SATA controller to avoid bus reset
User forums report issues when assigning ASM1164 SATA controllers to VMs,
especially in configurations with multiple controllers. Logs show the
device fails to retrain after bus reset. Reports suggest this is an issue
across multiple platforms. The device indicates support for PM reset,
therefore the device still has a viable function level reset mechanism.
The reporting user confirms the device is well behaved in this use case
with bus reset disabled.
