mtd: spi-nor: micron-st: add mt35xu01gbba support
mt35xu01gbba is similar with mt35xu512aba, but with two dies.
mt35xu01gbba has SFDP and support 8D-8D-8D mode, but SFDP
lack SNOR_F_IO_MODE_EN_VOLATILE, so add this fixup flags here.
Besides, mt35xu01gbba do not support chip erase, but support
die erase, so add that in late_init().
