* Remove remanants of legacy ARC FPGA platforms (AA4, ML509...)
* Only nsim simulation platform is left, rename platform accordingly
* AA4 DT stuff is compatible with nsim for ARC700 so rename it too

ARC GNU tools have had support for arc-linux-* driver for some time now.
This is functionally similar to arc-linux-uclibc-* but uclibc prefix
seemed weird at best when trying to compile the kernel itself.

Commit c00bfd974f ("ARC: [arcfpga] Get rid of legacy BVCI latency unit
support") removed the Kconfig symbol ARC_HAS_BVCI_LAT_UNIT. And that
symbol's entry was the only place were the symbols ARC_BOARD_ANGEL4 and
ARC_BOARD_ML509 were used. So ARC_BOARD_ANGEL4 and ARC_BOARD_ML509 can
be removed too.

Despite the switch to right UART driver (prev patch), serial console
still doesn't work due to missing CONFIG_SERIAL_OF_PLATFORM
Also fix the default cmdline in DT to not refer to out-of-tree
ARC framebuffer driver for console.

* DWARF unwinder related
+ Force DWARF2 compliant .debug_frame (gcc 4.8 defaults to DWARF4
which kernel unwinder can't grok).
+ Discard the additional .eh_frame generated
+ Discard the dwarf4 debug info generated by -gdwarf-2 for normal
no debug case
* 4.8 already uses arc600 multilibs for -mno-mpy
* switch to using uclibc compiler (to get -mmedium-calls and -mno-sdata)
and also since buildroot can only use 1 toolchain

This adds support for an ARC Virtual Platform. This platform is based on the
System C standard promoted by the OSCI (Open System C Initiative) and uses
nSIM to simulate the ARC CPU core itself.
Users can build a virtual SoC by combining System C models of peripherals
and CPU cores.
