flash/nor/nrf5: fix protection setting on nRF51

Protection setting has not ever worked. UICR CLENR0 register cannot
be simply written but has to programmed because it resides in UICR
page of the flash.

Enable flash programming before writing CLENR0 and set back to r/o
afterwards.

Inform the user that reset might be required.
