[IMX93][E39] Merge work of SECO NE and SECO Italy early review (MODV-159)

The new files need to be compiled with the kernel, as well as included in the U-Boot's seco-config tool to select the overlays. Due to this, the ticket requires 3 MRs, namely in Linux, the bootloader (U-Boot), and the meta-seconorth-machine layer (later CLEA-OS).
