LPC55xxx SoCs don't allow reading erased areas, the flash memory
controller (FMC) will trigger an ECC error for that area. To prevent
reading unwritten areas the low level FMC command of margin checking is
used, this will fail if the area to be read is not correctly written
(margin_check) or area is erased (blank_check).
In the case of an erased page, we return dummy data so the application
can program that area.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

Adds a new config HAS_MCUX_FTFX to conditionalize the mcux flash driver
on socs that support it. Selects HAS_MCUX_FTFX on all kinetis socs
except kw40z, because even though this soc has the relevant hardware,
its CMSIS header file is not compatible with the mcux flash driver in
ext/.
This change also prevents enabling the mcux flash driver on lpc and imx
rt boards.

Cleanup the Kconfig code for the flash driver. Platform-specific
options should be in their own Kconfig files to be consistent and to
not pollute the common configuration.
To this end we move the mcux options into it's own file.
