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.

-+ * Both AR2315 and AR2316 chips have PCI interface unit, which supports DMA
-+ * and interrupt. PCI interface supports MMIO access method, but does not
-+ * seem to support I/O ports.
-+ *
-+ * Read/write operation in the region 0x80000000-0xBFFFFFFF causes
-+ * a memory read/write command on the PCI bus. 30 LSBs of address on
-+ * the bus are taken from memory read/write request and 2 MSBs are
-+ * determined by PCI unit configuration.
-+ *
-+ * To work with the configuration space instead of memory is necessary set
-+ * the CFG_SEL bit in the PCI_MISC_CONFIG register.
-+ *
-+ * Devices on the bus can perform DMA requests via chip BAR1. PCI host
-+ * controller BARs are programmend as if an external device is programmed.
-+ * Which means that during configuration, IDSEL pin of the chip should be
-+ * asserted.
-+ *
-+ * We know (and support) only one board that uses the PCI interface -
-+ * Fonera 2.0g (FON2202). It has a USB EHCI controller connected to the
-+ * AR2315 PCI bus. IDSEL pin of USB controller is connected to AD[13] line
-+ * and IDSEL pin of AR2315 is connected to AD[16] line.
