ebe8b29bfa dma: fix Rx DMA suspend issue 
Issue:  DMA will be in suspend state if there is no buffer allocation
        happen to HW. If DMA is in suspend state, no interrupt will
        occur for channel which leads to not calling of
        osd_receive_packet().

Fix:    Whenever there is rx buffer kernel memory allocation failure, desc
        will be updated with reserve rx buffer. This reserved buffer is
	already allocated at the time of ether_open. Aim of same to
	make sure rx DMA always have buffer and not go in suspend state.

9f4bff9f10 osi: dma: Add callback for osd data path 
Issue:
When 2 OSD's are part of single compilation process, only one
OSD can be linked at compile time. This causes issues in handling
TX and RX communication from OSI to OSD.

Fix:
Add callbacks for TX and RX communication which can be registered by
OSD to receive callback communication from OSI for TX and RX. Use
existing API's if OSD doesn't register a callback.

Issue:
There is chance that descriptor is updated before Tail pointer is updated,
as former is memory operation and later is register operation and
sequence may no go in sync every time.

Fix:
Add memory barrier for stores to complete, after updating descriptor to
ensure that descriptor is indeed updated before register is written.

Fix: Drop Rx packets which are longer than currently set
MTU since HW cannot drop them.
