flash/nor/atsame5: Fix a timeout when erasing

According to the datasheet, erasing a block can take up to 200 ms.
When using a Segger J-Link with a 2 MHz clock the current loop
finishes after < 50 ms, ignores the timeout, and then fails when
erasing the next block.

Switch to a time based check, add an explicit yield, and report an
error on timeout.
