spi: spi-mem: Add DTR templates for cmd, address, dummy and data phase 

Setting dtr field of spi_mem_op is used when creating templates for
DTR ops in spinand.h. Also, 2 bytes cmd phases are required when
operating in Octal DTR SPI mode.

Create new templates for dtr mode cmd, address, dummy and data phase
in spi_mem_op, to set the dtr field to 1 and also allow passing the
nbytes for the cmd phase.
