em starterkit has two versions, 2.2 and 2.3.
Change soc.h to support both versions,
main changes are the interrupt connections.

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.

CONFIG_* usually come from Kconfig, rename variables that are locally
defined to avoid confusion about where they are set.

I2C_CLOCK_SPEED Kconfig option is DW driver specific. It does not
define I2C interface speed but rather the I2C DW module clock speed.
It is confusing for a user of any other I2C driver than DW.
This patch renames this option to I2C_DW_CLOCK_SPEED and makes it
visible only for DW I2C driver.

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.

PRIMARY, SECONDARY, NANOKERNEL, MICROKERNEL init levels are now
deprecated.
New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL
to replace them.
Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
where the documentation specified SECONDARY ran before the kernel started
up, but actually ran afterwards.

An implementation to flush multiple d-cache lines has been added
per the top-level cache.h API. ZEP-1153 was opened to express
the need for MORE i-cache and d-cache APIs. For example, the current
cache.h API doesn't provide a means to invalidate d-cache lines
and has nothing for i-cache.
I've also modified some of the i-cache related aux registers to have
better names so that they won't be confused with d-cache.
These changes are for
ZEP-1176.

We can derive NUM_REGULAR_IRQ_PRIO_LEVELS by subtracting 1
from CONFIG_IRQ_PRIO_LEVELS if FIRQ is present (which is currently
always the case). If FIRQ is not present, the value will be equal
to CONFIG_IRQ_PRIO_LEVELS since all interrupts will be regular.

EM7D was recently merged, and one change suggested there was
to remove conditional checks for NSIM. It is OK to have the simulator
use the exact same memory addresses and sizes as would be found on the
board. This submission fixes EM9D and EM11D to be the same -- i.e.
to not have NSIM conditionals.
See ZEP-966.

In order to add the EM7D SOC, I will be implementing a version of the FIRQ
interrupt handler that saves and restores registers on the stack when
RGF_NUM_BANKS==1. All other ARC SOCs at this time have RGF_NUM_BANKS==2,
allowing for a faster handler that can use the registers in the 2nd register bank.
But EM7D doesn't have this 2nd bank, hence the need for this new configurable choice.
