flash/nor/at91samd: add small delay before checking nvm status

OpenOCD's SWD subsystem doesn't currently have a consistent WAIT
handling (i.e. it doesn't ever retry, just returns an error), so right
after a row write a small delay is needed as AHB access is stalled
during the flashing operation.

The issue was exposed with a samd20 using ftdi SWD transport.
