* add arc mpu driver
* modify the corresponding kconfig and kbuild
* currently only em_starterkit 2.2's em7d configuration
has mpu feature (mpu version 2)
* as the minimum region size of arc mpu version 2 is 2048 bytes and
region size should be power of 2, the stack size of threads
(including main thread and idle thread) should be at least
2048 bytes and power of 2
* for mpu stack guard feature, a stack guard region of 2048 bytes
is generated. This brings more memory footprint
* For arc mpu version 3, the minimum region size is 32 bytes.
* the codes are tested by the mpu_stack_guard_test and stackprot

Add board metadata to be consumed by the sanitycheck script to provide
better matching with testcases and to test based on features declated in
the board files.

Due to support updated from 2.2 to 2.3, a debug script is provided
for emsk, so developer can directly debug the zephyr application
using commands such as follows.
+ make BOARD=em_starterkit debug

Here are the main changes:
* board: Update EMSK onboard resources such as Button, Switch and LEDs
+ update soc.h for em7d, em9d, em11d
+ update board.h for em_starterkit board
* arc: Add floating point support and code density support
+ add kconfig configuration
+ add compiler options
+ add register definitions, marcos, assembly codes
+ fixes in existing codes and configurations.
* arc: Update detailed board configurations for cores of emsk 2.3
* script: Provide arc_debugger.sh for debugging em_starterkit board
+ make BOARD=em_starterkit debug
This will start openocd server for emsk, and arc gdb will connect
to this debug server, user can run `continue` command if user just
want to run the application, or other commands if debugging needed.
+ make BOARD=em_starterkit debugserver
This will start an openocd debugger server for emsk, and user can
connect to this debugserver using arc gdb and do what they want to.
+ make BOARD=em_starterkit flash
This will download the zephyr application elf file to emsk,
and run it.

OPENOCD_PRE_CMD, OPENOCD_POST_CMD variables require adding
'-c' in front of an actual OpenOCD command. This is in contrary
to other OPENOCD_*_CMD varialbles which specify OpenOCD commands
directly. This patch aligns usage of various OPENOCD_*_CMD variables.
It is no longer required to add '-c' in front of OPENOCD_PRE_CMD,
OPENOCD_POST_CMD variables.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

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.

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.

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.

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.

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.
