mtd: spi-nor: core: Call spi_nor_post_sfdp_fixups() only when SFDP is defined
spi_nor_post_sfdp_fixups() was called even when there were no SFDP
tables defined. late_init() should be instead used for flashes that
do not define SFDP tables.
Use spi_nor_post_sfdp_fixups() just to fix SFDP data. post_sfdp()
hook is as of now used just by s28hs512t, mt35xu512aba, and both
support SFDP, there's no functional change with this patch.
