dadf9e7a81 xtensa: intel_s1000: implement interrupt mechanism
intel_s1000 has multiple levels of interrupts consisting of core, CAVS
Logic and designware interrupt controller. This patchset modifies
the regular gen_isr mechanism to support these multiple levels.

e3f2fa4f89 drivers: interrupts: introduce Designware interrupt controller
This interrupt controller is a designware IP that combines several
sources of interrupt into one line that is then routed to the parent
controller.

This implementation supports only the regular irqs with no support
for priority filtering and vectored interrupts. Firqs are also not
supported.

74016bb64c drivers: interrupts: introduce CAVS interrupt logic
CAVS interrupt logic is an intel IP that combines several sources of
interrupt into one line that is then routed to the parent controller.
CAVS stands for "connected Audio, Voice and Speech". This IP supports
4 lines which can have a max of 32 interrupts each.

57e80e5345 ext: mcux: Reorganize imported drivers into soc family subfolders
We have been combining imported mcux drivers into a flattened directory
structure to maximize driver reuse, but the introduction of additional
nxp soc families (lpc and imx) to zephyr has introduced driver naming
conflicts. This caused us to rename and modify imported files, such as
fsl_gpio.c/h, to make them unique across all three nxp soc families.
This makes updating the the mcux drivers complicated, especially for the
lpc family.

Reoganize the mcux drivers into soc family subfolders, so we can just
copy all the drivers from an mcux distribution (which is done on an
soc-basis) into the appropriate soc family folder. Undo all of the
naming changes that occurred when lpc and imx drivers were originally
imported. Undo the accidental squashing of the kinetis watchdog and dcdc
drivers that occurred when the imx drivers were introduced.

The drawback to this approach is that we have duplicate files when the
same hw ip modules exist in multiple soc families, however there are
only few cases where this occurs, such as fsl_lpuart and fsl_trng.

  uint32_t is defined as a parameter and internal Zephyr code attempts
  to use u32_t. If NewLib is used, the typedef for u32_t is
  'unsigned int' which is not a portable match to uint32_t as
  'unsigned int' is not a common size across architectures so gcc will

- The mcux flash code calls NXP supplied functions that expect a
