Subject: [PATCH v3 09/11] mtd: spi-nor: spansion: let SFDP determine the flash and sector size

sector_size is used to determine the flash size and the erase size in
case of uniform erase. n_sectors is used to determine the flash_size.
But the flash size and the erase sizes are determined when parsing SFDP,
let SFDP determine them.
