dmaengine: shdmac: use SET_RUNTIME_PM_OPS()
Use SET_RUNTIME_PM_OPS() to initialize the runtime PM method pointers in the
'struct dev_pm_ops'; since that macro doesn't do anything if CONFIG_PM is
not defined, we have to move #ifdef up to also cover the runtime PM methods
in order to avoid compilation warnings.
Based on orignal patch by Mikhail Ulyanov <mikhail.ulyanov@cogentembedded.com>.
