nrf51: fix UICR erase 

nrf51_erase_page() checks for (sector->offset == NRF51_UICR_BASE) to
determine if the UICR should be erased.  However, sector->offset for
the UICR bank is set to 0 in nrf51_probe, so this code is never hit.
Attempting to erase UICR ends up erasing the first flash sector.

Use bank->base instead to determine if UICR is being erased.
