This reverts commit 04b8edad262eec0d153005973dfbdd83423c0dcb.
mx25l51245g and mx66l51235l have the same flash ID. The flash detection returns the first entry in the flash_info array that matches the flash ID that was read, thus for the 0xc2201a ID, mx25l51245g was always hit, introducing a regression for mx66l51235l.
If one wants to differentiate the flash names, a better fix would be to differentiate between the two at run-time, depending on SFDP, and choose the correct name from a list of flash names, depending on the SFDP differentiator.
