Starting from nSIM 2019.06 is possible to use DW UART instead of ARC UART. That allows us to merge "nsim_hs" with "haps_hs" and "nsim_hs_smp" with "haps_hs_smp" with minor changes which were done in previous commits. We eliminate nsim_hs_defconfig and nsim_hs_smp_defconfig and leave haps_hs_defconfig and haps_hs_smp_defconfig which can be used on HAPS / nSIM / ZEBU / QEMU platforms without additional changes in Linux kernel. For nSIM we should now use UART property values "-prop=nsim_mem-dev=uart0,kind=dwuart,base=0xf0000000" instead of previously used "-prop=nsim_mem-dev=uart0,base=0xc0fc1000" "use_connect" and "irq" values of UART property remains untouched.
