arc: add Arcangel4 board support

Arcangel4 is a FPGA-based development board that is used for prototyping and
verificationof of both ARC hardware (CPUs) and software running upon CPU.

This board avaialble in 2 flavours:

  • Little-endian (arcangel4)
  • Big-endian (arcangel4-be)

7+# This board is mostly used for debugging U-Boot in simulation (ISS).
8+# The only peripheral which is used on this board is a serial port which
9+# requires no initialization except those in "include/configs/arcangel4.h".
10+# And now there's no specific initializations for this board.
11+# So this Makefile is only required for satisfaction of U-Boot build system.
