spi: cadence-qspi: put runtime in runtime PM hooks names

Follow kernel naming convention with regards to power-management
callback function names.

The convention in the kernel is:
 - prefix_suspend means the system-wide suspend callback;
 - prefix_runtime_suspend means the runtime PM suspend callback.
The same applies to resume callbacks.
