[PATCH 06/13] mtd: spinand: Add macros for Octal DTR page read and write operations

[Apurva Nandan <a-nandan@xxxxxx>]

Define new PAGE_READ_FROM_CACHE and PROG_LOAD op templates for Octal
DTR SPI mode. These templates would used in op_variants and
op_templates for defining Octal DTR read from cache and write to
cache operations.
