mtd: spi-nor-core: Fixup SNOR_F_IO_MODE_EN_VOLATILE for MT35X

Browse Source 
MT35XU512ABA has only BFPT and 4-Byte Address Instruction Table
in  SFDP. commit bebdc23750 ("mtd: spi-nor: Parse SFDP SCCR Map")
added checks in spi_nor_octal_dtr_enable() to bail out if the 22nd DWORD
in SCCR does not indicate DTR Octal Mode Enable, since MT35XU512ABA device
supports octal DTR mode, add this property in SFDP fixup.
