Eugeniy Paltsev 499b4c9069 ARC: nSIM: DTS: switch UART clock-frequency to 50MHz
UART IP is clocked with 50MHz on HAPS by default. So switch
UART clock-frequency from 100MHz to 50MHz for nsim_* boards
so the binaries can be run on HAPS as well.

This property is dummy in case run in simulator (nSIM) so we
don't need to change anything in nSIM configuration files.

Kumar Gala 77a56fd725 dts: remove incorrect use of device_type property
For true mmio-sram, arc,iccm, arc,dccm nodes we should not be setting
device_type = "memory".  This should be used for true DRAM regions of
memory and not on SoC SRAMs.

Eugeniy Paltsev 3eee762e08 ARC: NSIM: switch to ns16550 UART model
Switch nSIM from custom ARC UART to ns16550 model. That will
allow us to use zephyr images built for nSIM on other platforms
like HAPS, QEMU, etc...

This patch do:
 * switch nSIM board to ns16550 UART usage
 * change nSIM simulator configuration to use ns16550 UART model
 * drop checks for CONFIG_UART_NSIM in ARC code
 * update nSIM documentation

Kumar Gala b921955e44 boards: arc: nsim: cleanup dts warnings
Fix the following device tree warnings:

unit-address and first reg (0x40000) don't match for iccm@0
unit-address and first reg (0x80040000) don't match for dccm@80000000

Re-work iccm and dccm reg address and size to be based on #defines.
This allows the nsim_sem_normal.dts to override defaults that are set in
nsim.dtsi.  Utilize DT_ADDR macro to take a 'unit-address' still value
and convert it into a hex value (just prepending 0x).

Kumar Gala a5ae0daa35 dts: arc: Remove device_type = "memory" from {d,i}ccm nodes
The "{d,i}ccm" nodes should not have had a 'device_type' property.
Remove it from the cases that we clearly know are {d,i}ccm.

Alexey Brodkin c5663caf77 board/nsim: Refactor device tree description
Instead of blind copy of nsim_em.dts re-structure this way:
 * nsim.dtsi     - Top-level "board" description re-usable for
 |                 all nSIM-based "boards".
 |
 |                 Even though it's not needed right now but it
 |                 allows to add other ARC core families in the future.
 |
 \_ nsim_em.dtsi - Common definitions for boards with ARC EM cores
    |
    \_ Real boards with ARC EM cores
      |
      \ nsim_em.dts
      \ nsim_sem.dts
      \ nsim_em_mpu_stack_guard.dts
