2.3 Linux SDK Changes

The changes of the Linux SDK are mainly aimed at the modification of the C7 memory segment, which needs to correspond to it in the Linux DTS, otherwise an error occura when running on the board. The main modified files are: board-support/linux-5.4.74+gitAUTOINC+9574bba32a-g9574bba32a/arch/arm64/boot/dts/ti/k3-j721e-som-p0.dtsi and board-support/linux-5.4.74+gitAUTOINC+9574bba32a-g9574bba32a/arch/arm64/boot/dts/ti/k3-j721e-vision-apps.dtso.

Patch file 0001-upgrade-TIDL-to-8.4-memory-map-changes.patch, the complete changes are as follows:
