dt-bindings: mtd: jedec, spi-nor: Add DT property to avoid setting SRWD bit in status register

If the WP# signal of the flash device is either not connected or is wrongly
tied to GND (that includes internal pull-downs), and the software sets the
status register write disable (SRWD) bit in the status register then the
status register permanently becomes read-only. To avoid this added a new
boolean DT property "no-wp". If this property is set in the DT then the
software avoids setting the SRWD during status register write operation.
