mb/opencellular/elgon: Enable write protection
* Verify the flash write protection on each boot
* Program non-volatile write protection on first boot
Tested using I715791b8ae5d1db1ef587321ae5c9daa10eb7dbc.
The bootblock is write-protected as long as the #WP pin is asserted low:
* Reprogramming of the status register fails.
* Trying to write to WP_RO region fails.
Programming the WP_RO is only possible if #WP pin is high.
