As of now we have 2 flavors of ARC SDP boards:
1) AXS101 - with ARC770 in ASIC
2) AXS103 - with ARC HS38 in FPGA
Both options share exactly the same base-board and only differ with
CPU-tiles in use. That means all peripherals are the same (they are
implemented in FPGA on the base-board) and so generic board could be
used for both.
While at it:
* Recreated defconfigs with savedefconfig
* In include/configs/axs10x.h numerical sizes replaced with
defines from linux/sizes.h for better readability.

There're 2 versions of motherboards that could be used in ARC SDP.
The only important difference for U-Boot is different NAND IC in use:
[1] v2 board (we used to support up until now) sports MT29F4G08ABADAWP
while
[2] v3 board sports MT29F4G16ABADAWP
They are almost the same except data bus width 8-bit in [1] and 16-bit
in [2]. And for proper support of 16-bit data bus we have to pass
NAND_BUSWIDTH_16 option to NAND driver core - which we do now knowing
board type we're running on.
