Jeff Epler cacb0124ac feather_m4_express: Use quad data mode on flash 
Limor confirmed that the all shipping revisions starting with Rev D had QSPI flash chips installed.

Note that when neither EXTERNAL_FLASH_QSPI_SINGLE nor EXTERNAL_FLASH_QSPI_DUAL is specified quad mode is assumed, so this is addressed by removing the setting altogether.
