DesignWare MMC Controller's transfer mode should be decided
at runtime instead of compile-time. So we remove this config
option and read dw_mmc's register to select DMA master.

The AXS10x platforms consist of a mainboard with peripherals,
on which several daughter cards can be placed. The daughter cards
typically contain a CPU and memory.

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.

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.
