Peter Bigot 67808279fb drivers: flash: spi_nor: support devices that default to protect blocks 
Some SPI NOR devices, particularly Atmel and SST, power-up with block
protect bits set in the status register.  These bits must be cleared
before any erase or program operation can succeed.  However, blindly
clearing bits in SR is wrong as some of these are non-volatile and
control chip behavior, including quad-enable.

Add a devicetree flag to identify device-specific BP bits in the status
register that should be cleared on startup only for devices that need
them, and when set do the clear during initialization.
