Setting the status register write disable (SRWD) bit in the status
register (SR) with WP signal of the flash not connected will configure the
SR permanently as read-only. To avoid this a boolean type DT property
"broken-wp" is introduced. If this property is defined, the spi-nor doesn't
set the SRWD bit in SR while performing flash protection operation.
