imx-boot: generalize support for ccimx8x platforms with 1GB and 2GB of RAM
Generalize DCD patch to be agnostic of the platform and modify the imx-boot recipe to depend only on the memory configuration instead of the platform name. https://jira.digi.com/browse/DEL-6205 Signed-off-by: Arturo Buzarra <arturo.buzarra@digi.com>
