v1: Based on review comments from Daniel following changes are done.
- More focus is given for better synchronization.
- Replaced async firmware loading by using request_firmawre() call.
- Prevented entering in dc5/dc6 while firmware loading in process.
Now register programming for dc5/dc6 always will happen followed
by firmware loading.
- Removed the csr-lock and csr-state which was used before.
- Added a async work which is responsible for both loading the
firmware and register programming for dc5/dc6.
- Added flush_work() to explicitly synchronize the async work
during suspend and driver unloading.
- Corrected the sanity check for mmio address of csr (Requested by Imre).
- Removed assert call of csr during disabling dc6 (Requested by Damien).
