cf3364a363 arc770: Update kernel configuration
Now when we're switching to FS on SD-card it's necessary to have
full stack of MMC block & FC drivers built-in otherwise kernel won't
be able to mount FS with needed modules.

Also we enable parsing of input parameters passed to the kernel by
U-Boot. Otherwise kernel won't know where to look for command line and
what's worse device tree blob (we had to disable this by default for
cases when kernel is loaded by JTAG and core registers may have
undefined state lading to kernel going bonkers).

697ee80388 Revert "linux: arc: disable kernel unwinding to fix modules loading"
This reverts commit acd41539d6.

There's a fix in upstream that will at some point land in 4.4 stable as
well so we'll get rid of this hack and with the next commit will apply
upstream fix.

acd41539d6 linux: arc: disable kernel unwinding to fix modules loading
With update of binutils for ARC (this is now based on upstream 2.26)
we noticed issues with loadable kernel modules.

Something like that was happening:
--------------------->8-------------------
mbcache: unknown relocation: 49
insmod: can't insert './mbcache.ko': invalid module format
--------------------->8-------------------

More details could be found in that discussion in binutils mailing list:
http://thread.gmane.org/gmane.comp.gnu.binutils/74662

As of now the simplest work-around is to disable in-kernel unwinder
for now. That will at least allow us to use modules again.

9ef282cd96 arc770: enable unaligned access handling simulation in software
This enables misaligned access handling by software in Linux kernel.

With some wireless drivers (ath9k-htc and mt7601u for example) we see
misaligned accesses here and there and to cope with that without
fixing stuff in the drivers we're just gracefully handling it on ARC.

4514589182 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
