Hiroshi DOYU 8828880d09 omap: mailbox: Flush posted write when acking mailbox irq 
The only way to flush posted write to L4 bus is to do a read back
of the same register right after the write.

This seems to be mostly needed in interrupt handlers to avoid
causing spurious interrupts.

The earlier fix has been to mark the L4 bus as strongly ordered
memory, which solves the problem, but causes performance penalties.

Similar to the fix, 03803a71041e3bc3c077f4e7b92f6ceaa9426df3
