> JESD251, xSPI profile 1.0 table supports octal DTR mode.
> Extract information like the fast read opcode, dummy cycles for various
> frequencies, the number of dummy cycles needed for a Read Status
> Register command, the number of address bytes needed for a Read
> Status Register command, read volatile register command and write
> volatile register command.
> 
> According to BFPT 20th DWORD of octal maximum speed, driver get it's
> specific dummy cycles from profile 1.0 table and then could update
> it to device by their fixup hooks.
> 
> Since driver get octal DTR read opcode and then set read settings,
> expose spi_nor_set_read_settings() in core.h.
