Remove legacy option and use SYS_CLOCK_EXISTS where appropriate.

Chuck Jordan 5fbbe44883 arc: em_starterkit default changed to EM7D
ZEP-1317 records a problem were em_starterkit appears to boot up
EM7d, sometimes, due to a misread of the dip-switches.
This could be a mechanical issue. I am seeing it on my board too,
and I often have to struggle with the dip-switch to get it to boot
EM9D. For automated-testing, perhaps it is better if the default is
EM7D, since this is the all-switches-up and contact in the switch
isn't needed. Meanwhile, I'll work with our board team to try to get
to the bottom of this.

ZEP-1317

Chuck Jordan 314d94e7f8 arc: 1msec tick gives more stable scheduling
I notice that many of the other boards here use 1msec for the tick.
I notice also that when switching to unified kernel, scheduling based
on time has a lot more jitter with a 5msec tick.

I think a better default is 1000 ticks per second for em_starterkit.

Anas Nashif 813d550361 [REVERTME]boards: omit frame pointer for ARC boards
The current ARC GCC compiler used in Zephyr SDK v0.8.2 generates
incorrect code when using the "-fno-omit-frame-pointer" option. This bug
should have been fixed in the 2016.03 release of the compiler.

Chuck Jordan 669d581e0a arc: Let CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC be set by SOC
The value for CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC needs to be set
in the SOC, since each SOC will have a different frequency
on the EM Starterkit. The EM7D, for example, has a 30Mhz CPU clock.
It was already being defined in the SOC, but the board setting
would override the SOC.

Kumar Gala 8d35760fec board: organize boards based on architecture
Introduce an architecture sorting of boards.  This is to allow for
easier maintenance going forward as the number of boards grows.  It
will be easier for any scripts to know the board/arch mapping without
having to maintain an explicit list of what boards are associated with
which arch.  We can also do things like have architecture maintainers
cover reviews and branches for arch/${ARCH} and boards/${ARCH} going
forward.
