Subject: [PATCH v3 02/17] mtd: spinand: Define macros for Octal DTR ops

Define new op templates for reset, write enable, set_feature,
get_feature, block_erase, read/write page operations for Octal DTR SPI
mode. These templates will be used in data_ops and ctrl_ops for
performing all flash operations.
