n25q variants do not support stateless 4 byte addressing opcodes by default,
therefore first patch disables this flag for those parts. Second patch
adds entries for mt25q variants which are similar to n25q but supports
stateless 4 byte opcodes. Third patch adds USE_FSR flag for mt25q* and
n25q* variants where missing

Changes since v2:
Add USE_FSR flags to all flash variants where missing
Collect T-bys and R-bys
Reword commit msgs as necessary

Changes since v1:
Rename newer variants as mt25*
Add a patch to enable flag register parsing for mt25qu512a

Vignesh Raghavendra (3):
  spi-nor: spi-nor-ids: Disable SPI_NOR_4B_OPCODES for n25q512* and
    n25q256*
  spi-nor: spi-nor-ids: Add entries for mt25q variants
  spi-nor: spi-nor-ids: Add USE_FSR flag for mt25q* and n25q* entry
