[PATCH v3 2/2] ARM: imx: imx8mn-evk-common-u-boot.dtsi: cleanup

This cleanup implements several review comments and its target is to
prepare for a common imx8mn-common-u-boot.dtsi for all imx8mn boards.
It includes changes in node names to use only dashes instead of
underscores, improve the odd bloob-ext naming, use the atf-bl31 type and
the use of of-list for multiple DTB support.
