When CONFIG_SYS_POWER_DEEP_SLEEP is enabled, i2c_qmsi_ss will
keep entering deep sleep because it needs to wait until the
current transfer completes, which blocks the current thread.
The system keeps entering deep sleep again and again and the
transfer will never complete.
Add device_busy_set() to i2c_qmsi_ss driver to indicate that
the device is busy and block the system from entering deep
sleep during transaction.

Enable arc to access the i2c controller on I/O fabric.
There are two i2c controllers on quark se SoC. One is attached
to the I/O fabric and the other one is in the sensor system.
X86 cpu is only able to access the i2c controller on the I/O
fabric and the access is supported by existing code. HW allows
arc to access both controllers. But, the existing code only
gives arc access to the controller in the sensor sub-system.
Let's grant arc the access to the controller on I/O fabric as
well by the following changes.
1. Add i2c_qmsi.c into arc compilation.
2. Use the already defined macros to choose interrupt numbers
and do interrupt unmasking automatically based on the
compilation targets.
3. Add new symbols in Kconfig including driver names for both
controllers

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.

Update the QMSI drop we maintain in Zephyr, and fix the build where
needed:
- QM_SCSS_INT is renamed to QM_INTERRUPT_ROUTER;
- every member of QM_INTERRUPT_ROUTER was renamed as well;
- QM_IRQ_* renamed too, mostly added _INT at the end;
- some isr functions were renamed to keep their names consistent;
- build for x86 needs to define QM_LAKEMONT, as QM_SENSOR was for ARC.

PCI enumeration modifies pci_dev, base_addaress at driver
initialization therefore this objects move from config_info to
driver_data in preparation for config_info becoming const..
We drop code that attempts to update irq_num based on PCI enumeration
because the interrupt found by PCI enumeration must always be the same
as the statically configured IRQ number.

In order to restore i2c context after entering
SYS_PM_DEEP_SLEEP, suspend and resume functions
are called.
The following parameters are restored:
- All registers for the I2C device.
- I2C clocks.
I2C depends on the DMA which is enabled separately.
The suspend/resume functionality is implemented in
the QMSI shim layer as a fast and temporary solution,
it will be removed and migrated to QMSI later.

Fix a compilation warning. Compilation of the i2c driver
requires QMSI dma object file. As a solution, the current
code has "selects DMA_QMSI" in i2c Kconfig. This results
in a compilation warning since "select DMA" is also
required. Adding "select DMA" and "select DMA_QMSI"
together in i2c Kconfig can solve the compilation issue.
But, this will cause the dma driver be unnecessarily
enabled. So, the solution is to fix the issue in the QMSI
part instead of in the shim driver.

way to check whether i2c master is ready to transfer data. If

stop condition is not sent by the previous API, the i2c master
is not idle, but, it can start new data transfer.
