SPI: opmenu special case for WREN as atomic prefix

The code that attempts to use the opmenu needs to have a special
case for write enable now that it is handled as an atomic prefix
and not as a standalone opcode.

To test, ensure that runtime SPI write via ELOG is successful by
checking the event log for a kernel shutdown reason code:

5 | 2012-08-27 11:09:48 | Kernel Event | Clean Shutdown
6 | 2012-08-27 11:09:50 | System boot | 26
7 | 2012-08-27 11:09:50 | System Reset
