arc770: bump linux kernel from 4.3 to 4.4
This switch involved: [1] Regeneration of config (few options went away) [2] Regeneration of patches so they apply cleanly (different offsets) [3] Update of .dts files because we now explicitly specify memory regions in use as opposed to previously used offset from 0x8000_0000 Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Felix Fietkau <nbd@openwrt.org> Cc: Jo-Philipp Wich <jow@openwrt.org> Cc: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 48240

+Subject: [PATCH 1/2] openwrt: arc - remove dependency on DEVTMPFS
+
+OpenWRT builds initramfs so that it doesn't require DEVTMPFS so dropping
+this dependency. That helps to escape 2 separate kernel rebuilds with
+and without initramfs.
+
+2 builds happen because OpenWRT first builds kernel and later modules.
+When building entire kernel with simple "make" INITRAMFS sets to a real
+value and so was triggering DEVTMPFS selection. Then when building only
+modules with "make modules" command INITRAMFS is zeroed and so kernel
+config was changing that lead to full kernel rebuild.
