media: sunxi: fix pm_runtime_get_sync() usage count

Browse Source 
[ Upstream commit 9c298f82d8392f799a0595f50076afa1d91e9092 ]

The pm_runtime_get_sync() internally increments the
dev->power.usage_count without decrementing it, even on errors.
Replace it by the new pm_runtime_resume_and_get(), introduced by:
commit dd8088d5a8 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter")
in order to properly decrement the usage counter, avoiding
a potential PM usage counter leak.
