spi: spi-mem: Limit octal DTR constraints to octal DTR situations
In this helper, any operation with a single DTR cycle (like 1S-1S-8D) is
considered requiring a duplicated command opcode. This is wrong as this
constraint only applies to octal DTR operations (8D-8D-8D).
Narrow the application of this constraint to the concerned bus
interface.
Note: none of the possible XD-XD-XD pattern, with X being one of {1, 2,
4} would benefit from this check either as there is only in octal DTR
mode that a single clock edge would be enough to transmit the full
opcode.
Make sure the constraint of expecting two bytes for the command is
applied to the relevant bus interface.
