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).
