mtd: spi-nor: Fix selection of 4-byte addressing opcodes on Spansion

Browse Source 
commit 440b6d50254bdbd84c2a665c7f53ec69dd741a4f upstream.

mtd->size is still unassigned when running spansion_post_sfdp_fixups()
hook, therefore use nor->params.size to determine the size of flash device.

This makes sure that 4-byte addressing opcodes are used on Spansion
flashes that are larger than 16MiB and don't have SFDP 4BAIT table
populated.
