ath25: update kernel from 3.18 to 4.4

Summary of changes:
	* moved config-3.18 to config-4.4 and patches-3.18 to patches-4.4
	* removed most of the first two patches, that seem to be upstream already
	* changed deprecated/removed IRQF_DISABLED to zero following examples in upstream kernel patches
	* added config line to disable device-tree to satisfy kernel configuration
	* add new image generation code

Build tested and run tested on an Accton MR3201A.
