MALI: bifrost: Change clock source to normal pll when suspend

Browse Source 
When call pm_runtime_get_sync(), the runtime callback will change clock
source to normal pll, but now pm_runtime_get_sync() is called in a delay
work and the wakelock seems to be invalid on linux system,
so when suspend the pm_runtime_get_sync() may not be called.
