d73045826a target/archs38: switch to 4.9 kernel
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.

334fdea08d archs38: Merge sd and ramfs subtargets in generic again
As it turned out we may actually build both initramfs and
SD-based images in one run with just a small tweak in
existing image/Makefile and so we do here.

We're back with one "generic" target for all ARC HS38-based bords.

Kudos to John for his patience and very helpful tips!

df4f41261c archs38: Introduce images for SD-cards
Historically on ARC we started from initramfs-based images because:
 a) It was much easier to debug especially when toolchain and other
    components were changing quite dynamically
 b) It was our usual approach for embedded Linux

But now with ARC port of Lede/OpenWRT getting more stable and mature
we're ready for more real-life scenarios with FS permanently stored
on SD-card. This essentially benefits from ability to setup devices
that survive reboots with all settings and extra packages kept in place.

Still we keep an ability to build images with initramfs.
This allows us to use storage-less simulators for testing still.

73015c4cb3 linux: add support of Synopsys ARCHS38-based boards
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.
