crypto: qce - Add runtime PM and interconnect bandwidth scaling support

Browse source

The Qualcomm Crypto Engine (QCE) driver currently lacks support for
runtime power management (PM) and interconnect bandwidth control.
As a result, the hardware remains fully powered and clocks stay
enabled even when the device is idle. Additionally, static
interconnect bandwidth votes are held indefinitely, preventing the
system from reclaiming unused bandwidth.

Address this by enabling runtime PM and dynamic interconnect
bandwidth scaling to allow the system to suspend the device when idle
and scale interconnect usage based on actual demand. Improve overall
system efficiency by reducing power usage and optimizing interconnect
resource allocation.
