arc: Rename AXS101 board to more generic AXS10x
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.
