Adds support for XT25F128B used on Odroid Go Advance. Unfortunately this chip uses a continuation code which I cannot seem to parse, so there are possibly going to be collisions with chips that use the same manufacturer/ID.

Upon closer inspection of the datasheet, I'm almost certain the SPI_NOR_HAS_LOCK or the SPI_NOR_HAS_TB doesn't need to be set here. While the chip I think has these features, the bits are different than what is expected by these flags. I've been testing the Linux and U-boot drivers without these flags with no problems.
