Otherwise we have a race condition with wr_date setting initial time on the
switch.

Add checking stack overflow and detecting reset to wrs. Code common for wrpc
and wrs is placed in system_checks.c and .h. Work is based on following
commits in wrc_main.c:
1704a668 main: check for stack overflow
7836c39e

 Optionally detect reset and print a stack trace

Additionally:
--update Kconfig to have a possibility to select CHECK_RESET also for switch,
  not only for node as before
--and _endram to ram-wrs.ld

When "stack overflow" occurs then message is printed once every second.
When reset occours then LM32 will print stack trace and reset once more.
NOTE: I couldn't get spll to work after reset, for sure problem is in
      ad9516 init function, but not only there.

By default the scb_ver is "33" but it can be modified at runtime in order
to load the config for SCB v3.4 (i.e, load-lm32 rt_cpu.elf scb_ver=34)

This fixes a missing symbol and another minor header issue.  Needed to
build for wr-switch.

The commit is part of the effort in unifying softpll with
wr-switch-sw, and later remove the duplicated code there.

The files added by these commit are going to be built when configuring
wrpc-sw to build wr-switch rt_cpu (which is, basically, the softpll
code alone, with mini-rpc with the host and the basic glue code).  The
files are copied with the original name with two exceptions:

   wr-switch-sw::rt/main.c            becomes wrpc-sw::wrs_main.c
   wr-switch-sw::rt/arch/lm32/ram.ld  becomes wrpc-sw::arch/lm32/ram-wrs.ld

The files are copied from commit FIXME of wr-switch-sw.

This commit has no technical effect, as the files are not built for wrpc-sw.
