soc: qcom: rpm: Change driver memory allocation to use GFP_NOIO
When a filesystem driver calls into makes a RPM request, RPM driver
makes a kzalloc request with GFP_NOFS flag. This results in a
deadlock if a driver waiting on IO completion sends a RPM message.
Change memory allocation in the RPM driver to use GFP_NOIO.
