Subject: [PATCH 0/2] Fix usage counter leak by adding a general sync ops

Many caller forget to decrease the usage counter when call
pm_runtime_get_sync. This problem has been discussed in detail,
[0][1] and we add gene_pm_runtime_get_sync ops to deal with usage
counter for better coding. Then, we replace pm_runtime_get_sync
with it in fec_main.c
