Vineet Gupta 33460f86ad ARC: [plat-sim] Include this platform unconditionally
Essentially remove CONFIG_ARC_PLAT_SIM

There is no need for any platform specific code, just the board DTS
match strings which we can include unconditionally

Vineet Gupta 8ba605b607 ARC: [plat-*] ARC_HAS_COH_CACHES no longer relevant
A typical SMP system expects cache coherency. Initial NPS platform
support was slated to be SMP w/o cache coherency.

However it seems the platform now selects that option, so there is no
point in keeping it around.

Vineet Gupta 9efac6798b ARCv2: Add support for ZeBu Emulation platform for HS cores
The cool thing is that same kernel image can run on
 - nsim OSCI simulation platform
 - SDPlite FPGA setups

Vineet Gupta aa0efcde45 ARCv2: smp: [plat-*]: No need to explicitly call mcip_init_smp()
MCIP now registers it's own per cpu setup routine (for IPI IRQ request)
using smp_ops.init_irq_cpu().

So no need for platforms to do that. This now completely decouples
platforms from MCIP.

Vineet Gupta 26b8f99623 ARCv2: smp: [plat-*]: No need to explicitly call mcip_init_early_smp()
MCIP now registers it's own probe callback with smp_ops.init_early_smp()
which is called by ARC common code, so no need for platforms to do that.

This decouples the platforms and MCIP and helps confine MCIP details
to it's own file.

Vineet Gupta fd1557923b ARC: [plat_arcfpga]->[plat_sim]
* 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
