[PATCH v3 02/23] mtd: spi-nor: Create a structure containing the flash opcodes

[Takahiro.Kuwano at infineon.com]

> Create a structure named opcodes in the flash parameters structures to
> store all the flash specific opcodes. They are typically discovered
> dynamically through SFDP parsing. Move the die_erase opcode
> inside. Later on we will add new fields there, like the supported
> opcodes for accessing the status registers, which are almost vendor
> specific.
> 
> No fonctional change.
