mtd: spi-nor: micron-st: add SNOR_CMD_PP_8_8_8_DTR sfdp fixup for mt35xu512aba
Find two batches mt35xu512aba has different SFDP but with same
jedec ID. The batch which use the new version of SFDP contain
all the necessary information to support OCT DTR mode. The batch
with old version do not contain the OCT DTR command information,
but in fact it did support OCT DTR mode.
Current mt35xu512aba_post_sfdp_fixup() add some setting including
SNOR_CMD_READ_8_8_8_DTR, but still lack SNOR_CMD_PP_8_8_8_DTR. Meet
issue on the batch mt35xu512aba with old SFDP version. Because no
SNOR_CMD_PP_8_8_8_DTR, micron_st_nor_octal_dtr_en() will not be
called, then use SNOR_CMD_READ_8_8_8_DTR will meet issue.
