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.
