Adds dts bindings for the mcr20a wireless transceiver. The frdm_k64f
board supports the mcr20a via an Arduino shield, therefore the dts node
is added to the board dts. The kw2xd is a SiP and thus the mcr20a dts
node is added to the soc dts.
The networking samples using prj_frdm_k64f_mcr20a.conf have been broken
since the refactoring of the mcux gpio driver to dts in commit
4e8f29f319. The sample is now fixed.

Until now, Zephyr has used a patched Kconfiglib that turns 'source' into
a globbing source (by replacing 'source' with 'gsource' at the token
level). There's two problems with this:
- The patch needs to be maintained separately
- Misspelled filenames are silently ignored, as they look like glob
patterns that don't match anything
Fix it as follows:
1. Replace all 'source' statements that use wildcards with 'gsource'
2. Remove the custom Kconfiglib patch so that 'source' no longer globs
The sed pattern '/source.*[*?]/s/source/gsource/' was run over all
Kconfig* files to do the replacement.
source's that use environment variables that might contain glob patterns
were manually changed to gsource.
Building the docs in doc/ is a good test, as doc/Makefile deliberately
sets the environment variables to glob up as many Kconfig files as
possible.

The pinmux subsystem does not have any API documenation. Currently
none of the existing pinmux drivers do any kind of input validation
for the pin/op parameters, which has been shown to allow the caller
to access unauthorized memory, up to and including disabling the
MPU.
This requires a proper specification for the pinmux subsystem and
also modification of existingd drivers to validate arguments on a per
driver basis. Remove user mode access until #7390 is resolved.

DMA IP but the register offset and bits have been changed in some
cases. However, the fundamental definition for the register field
has not been changed. Hence the registers begin with "DW_" to

This driver currently supports the single block mode and linked list
multi-block mode. Scatter-Gather is not supported.

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.
