soc: arm: nxp_imx: don't default CONFIG_DEVICE_CONFIGURATION_DATA=y

Don't default CONFIG_DEVICE_CONFIGURATION_DATA to enabled for iMX RT
SOCs, as this configuration block is only used when the board needs
peripherals like the external memory controller setup from reset by the
bootrom.

Enable this feature on all in tree boards that will require it,
and document the change to the default value in release notes.
