I2C_SHARED_IRQ, I2C_0_IRQ_SHARED, I2C_0_IRQ_DIRECT Kconfig options
are DW driver specific. Its presence is confusing for a user of any
other I2C driver than DW. This patch renames these options to include
DW string and makes it visible only for DW I2C driver. This is a
similar implementation to that used by ETH DW Ethernet driver.

This commit removes unnecessary CONFIG_SYS_POWER_DEEP_SLEEP protection
in shim drivers as QMSI 1.4 has introduced empty context save/restore
functions that can be called in Quark D2000, therefore keeping common
code at the shim driver level for Quark SE and D2000.

The DW i2c driver chooses to return -EPERM following a PCI error in
driver configuration. This seems an odd choice. All of the other I2C
drivers return -EIO for general failures detected during driver
configuration.
Switch the DW driver from EPERM to EIO.

The I2C drivers handle an empty list of I2C messages inconsistenty.
There are two different behaviours, one set of drivers dectects a
requests to transfer zero messages and return -EINVAL while the other
group simple transfer no data and return success.
Adopt the latter behaviour consistently across all drivers. Update
the i2c.h API documentation to reflect this behaviour.

When CONFIG_I2C_0_IRQ_DIRECT=y, it is acceptable to just
pass the constant to irq_enable.

Basic interrupt driven i2c driver for the NRf5 series.
The NRf5 series hardware imposes a constraint that various peripherals
cannot be used simultaneously. This driver does not implement mutual
exclusion against SPI, or SPIs drivers (yet).

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.

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

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

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.
