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.
