Subject: [PATCH 0/4] mtd: spi-nor: micron-st: add die erase for micron spi
 nor chip

mt35xu02gcba, mt35xu01gbba and mt35xu512aba are similar, but with
different number of dies. According to the datasheet:
https://datasheet.octopart.com/MT35XU02GCBA1G12-0AAT-Micron-datasheet-138896808.pdf
these chips all support die erase command, but do not support chip
erase. So change the drivers accordingly.
Also add mt35xu01gbba support here, test this chip on imx95-19x19-evk
board, it works under 200MHz at 8D-8D-8D mode.
