With update of ARC tools to arc-2016.09 based on GCC v6.x
we have to bump Linux kernel version so both toolchain and
the kernel use the same ARC ABIv4.

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).

This reverts commit acd41539d630688e9891003c9b51cace3e113316.
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.

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.

This patch introduces support of new boards with ARC HS38 cores.
ARC HS38 is a new generation of ARC cores which utilize ARCv2 ISA.
As with ARC770 we're addind support for 2 boards for now:
[1] Synopsys SDP board (AXS103)
This is the same base-board as in AXS101 but with
FPGA-based CPU-tile where ARCHs38 core is implemented.
[2] nSIM
Again this is the same simulation engine but configured for
new instruction set and features of new CPU.
