accel/amdxdna: Resume power for creating and destroying hardware context

Browse Source 
When the hardware is powered down by auto-suspend, creating or destroying
a hardware context without resuming power will fail.
Call amdxdna_pm_resume_get() before requesting the hardware to create or
destroy a hardware context.
