Add few nop instructions to allow the DMA controller settle,
It takes time after starting the transfer to access the DMA
controller registers, so a few cycles are added, the minimal number
of cycles needed has been calculated using tests results on c1000
development board.

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.

Update the qmsi dma shim driver based on the new dma api
interface.
Recently, a RFC was posted to update the dma api. The update
to dma api interface was already posted. This change is to
update the dma qmsi shim driver based on the dma api change.
It is using the new data structures and new api function names.

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.

Add the necessary infrastructure to support power management for the
QMSI DMA driver. If deep sleep is supported, this driver supports
saving its context to be restored on resume.

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.

Set DMA transfer to QM_DMA_TYPE_SINGLE for all channels.
This keeps the previous behavior as of QMSI 1.1.
In the future, we may consider adding support for using other DMA
transfer types. This, however, will demand adding new API to Zephyr's
dma.h .

Add typecasting in dma QMSI shim to avoid compilation error.
The DMA API and QMSI have their own definitions for the
dma configuration parameters, such as handshake_interface,
handshake_polarity, source/destination_transfer_width,
channel_direction, and source/destination_burst_length.
When a API is called, the shim driver will assign values
for the above-mentioned parameters to the configuration
variable(based on QMSI's definiton) from the values in the
variable provided by the caller based on API's definition.
Even though all these parameters have similiar definition
and values in both the generic API and QMSI, QMSI uses
its own names which are different from those definied in
the generic API. Without typecasting, the parameter value
assignment will cause compilation error(even though error
only happens for some compiler).
