[RFC PATCH v2 01/12] spi: dt-bindings: add spi-has-dqs property

[Santhosh Kumar K]

Add the optional 'spi-has-dqs' boolean property for SPI flash device
subnodes. This property indicates the flash device supports DQS (Data
Strobe) mode, which provides improved timing margins for data capture
in high-speed SPI operations.
