When going into DEEP_SLEEP mode, the ARC core now saves
its context. This includes:
- All core registers
- Stack pointer
- Program counter (restored by jumping to the restore code)
The arc reset code now checks if the GPS0 bit 2 is set.
This is similar to the behavior of the x86 core done by
the QMSI bootloader which is setting GPS0 bit 1 in order
to call the restore path instead of cold boot path.
The sample has been adapted in order to support the ARC.

tests: power_states app updated to support SoCWatch collection
Add CONFIG_SOC_WATCH option for enabling the SoCWatch
QMSI driver and associated instrumentation hooks.
Bug fix for soc_watch.c to use local irq_lock/unlock
This will be put into QMSI as well.

The API to disable _sys_soc_resume notification is currently
called _sys_soc_disable_wake_event_notification. This is
misleading because it is possible that the ISR from which
_sys_soc_resume is called could be from a different interrupt
with higher priority that happened before interrupts were
enabled. More accurately, it is a notification of exit from
kernel idling after pm operations.

Add Low Power States support to the power shim layer
and show the usage in the quark_se sample.
States are defined as follow:
- SYS_POWER_STATE_CPU_LPS: SS2 with LPSS enabled
- SYS_POWER_STATE_CPU_LPS_1: SS2 with LPSS disabled
- SYS_POWER_STATE_CPU_LPS_2: SS1 with LPSS disabled

QMSI 1.3 natively supports restoring the SoC and peripherals
after sleep.
The Zephyr Power Management shim layer is updated
in order to support QMSI functions.
The following functions have been added:
void _sys_soc_set_power_state(enum power_state);
void _sys_soc_power_state_post_ops(void);
In order to fully support deep sleep, the function
_sys_soc_set_power_state now support saving and
restoring CPU context and returns to the application.
_sys_soc_set_power_state function also abstracts
QMSI cpu states and enable the application to choose
between C1/C2 or C2LP states.
The QMSI power states are mapped as follows:
SYS_SOC_POWER_STATE_CPU_LPS -> power_cpu_c2lp
SYS_SOC_POWER_STATE_CPU_LPS_1 -> power_cpu_c2
SYS_SOC_POWER_STATE_CPU_LPS_2 -> power_cpu_c1
SYS_SOC_POWER_STATE_DEEP_SLEEP -> power_soc_deep_sleep
SYS_SOC_POWER_STATE_DEEP_SLEEP_1 -> power_soc_sleep
The following functions have been removed:
void _sys_soc_set_power_policy(uint32_t pm_policy);
int _sys_soc_get_power_policy(void);
FUNC_NORETURN void _sys_soc_put_deep_sleep(void);
void _sys_soc_put_low_power_state(void);
void _sys_soc_deep_sleep_post_ops(void);
Those changes are propagated to the samples.
All calls to QMSI are removed.
