Improve PNOR DD Micron NOR Workaround
Improving the workaround implemented in Story 53201 to be more
efficient. Changing to use the normal SFC polling to determine
when the write/erase operations are complete and then reading
the Micron Flag Status register once to keep the chip from
getting into a bad state. This should reduce the traffic on the
SPI bus.
