So, the da850evm is for the OMAP-L138 and da850_am18xxevm is for the
AM18xx EVM.  However, the config split was done, I believe, but folks on
the L138 side and might not have been tried fully on the am1808.  So
since you've got the AM1808 and can test it there, lets add the missing
SPI_FLASH define too.  I think my coworker that did a quick non-SPL
check of the code the other week also noted SPI wasn't supported.
