soc: qcom: Request GFP_NOIO for effective memory reclaim

Request for memory with GFP_NOIO so that new IO
request is not raised while reclaiming the memory when
system is having low memory. With GFP_KERNEL a deadlock
is possible with scm function requsting for memory during
PFK operation intiated by block layer through storage
driver. With low memory system will try to
reclaim some memory. If GFP_KERNEL is used this
will lead to IO operation through storage driver
which is already serving PFK encryption call hence
can not take up this IO request causing deadlock.
