[edk2-platforms Patch V2 1/6] Styx/PlatformFlashAccessLib: Add progress API

["Kinney, Michael D" <michael.d.kinney@intel.com>]

https://bugzilla.tianocore.org/show_bug.cgi?id=801

Add PerformFlashWriteWithProgress() to the PlatformFlashAccessLib.
This allows the platform to inform the user of progress when a
firmware storage device is being updated with a new firmware
image.
