mfd: arizona: Fix rumtime PM imbalance on error

Browse Source 
[ Upstream commit fe6df2b48043bbe1e852b2320501d3b169363c35 ]

pm_runtime_get_sync() will increase the rumtime PM counter
even it returns an error. Thus a pairing decrement is needed
to prevent refcount leak. Fix this by replacing this API with
pm_runtime_resume_and_get(), which will not change the runtime
PM counter on error.
