LVDS support

This MR contains the first part of fixes, which are specific to U-Boot and device tree, to make LVDS work and to be auto detected.

Following changes are included in this MR:

• "touch_rst_gpio" was actualized to iMX93 SOM in U-Boots environment;
• kernel configuration options, which are required for operation of LVDS, were enabled
• "imx93-kontron-dl.dtbo", which enables lcif and ldb drivers, was added to the KERNEL_DEVICETREE list
• UBOOT_DTB_LOADADDRESS and UBOOT_DTBO_LOADADDRESS were updated to make default and LVDS configurations/overlays provided via fitImage work

Notes:

• touch screen did not work on available displays, so TS functionality was not tested
• as TS did not work, it was not possible to determine which display is connected, so an overlay for specific display was manually activated in U-Boot
