[PATCH v4 4/4] cxl/mem: Disable cxl device power management

[Dan Williams]

There is no power management of cxl virtual devices, disable
device-power-management and runtime-power-management to prevent
userspace from growing expectations of those attributes appearing. They
can be added back in the future if needed.
