[PATCH RESEND 2/2] soc: qcom: stats: Mark device as having no PM support

[Stephen Boyd]

This driver purely exposes information from memory to the kernel. Let's
mark it as not having any device PM functionality, so that during
suspend we skip even trying to call a suspend function on this device.
This clears up suspend logs more than anything else, but it also shaves
a few cycles off suspend.
