spi: spi-mem: Transform the read operation template

As of now, we only use a single operation template when creating SPI
memory direct mappings. With the idea to extend this possibility to 2,
rename the template to reflect that we are currently setting the
"primary" operation, and create a pointer in the same structure to point
to it.

From a user point of view, the op_tmpl name remains but becomes a
pointer, leading to minor changes in both the SPI NAND and SPI NOR
cores.

There is no functional change.
