dragon-nx32: SPI fast sector read: Initiate bit shifting after FRX enable

In the fast receive mode (FRX) of the 65SPI interface a read of
the data register triggers reading in the next byte over SPI. So
after going into this mode the first read will return the value
that was already there, before shifting in of the new value ensues.
