[PATCH 3/3] mtd: bcm47xxsflash: define opcodes

[Rafał Miłecki]

We need them to add erase/write support. This may duplicate some defines
with bcma and/or ssb code, but it makes more sense to keep that in
bcm47xxsflash which is supposed to work with both buses.
Duplicated defines will be removed from ssb/bcma.
