spi: spi-mem: Flag DQS capability

Browse source

DQS is a typical SPI memory signal used to help with reading the data on
the bus at high speeds (especially in DTR mode) by avoiding clock
skews. The chip generates a clock signal synchronized with its data
output fronts, also called data strobe.

SPI NOR and SPI NAND cores must set this flag in order to indicate to
other layers that DQS is available.

Create a getter and a setter to reach this capability.
