The flash on the Integrator was already defined by the device tree, but VPP control and flash protection was in the boardfiles. Simply add the compatible string "arm,versatile-flash" and the special add-on code for flash programming voltage and protection kicks in in the MTD layer. Remove the board file code and augment the device tree in one go for seamless transition.
