ArmPlatformPkg/NorFlashDxe: prepare for devicepath format change
A subsequent patch will change the layout of devicepath nodes
produced by this driver. In preparation, make some tweaks to
the code to use a packed struct for the devicepath and to pass
the device index to NorFlashCreateInstance(). These are cosmetic
changes only, the resulting binaries should be identical.
