In Linux v6.2, the Tegra IVC driver was updated to support iosys-map and this breaks building some of the out-of-tree drivers for Linux v6.2+ kernels. In Linux v6.3, the GPIO OF APIs were removed and this breaks building some of the out-of-tree drivers that use these legacy APIs. For now the broken drivers are not built for these corresponding kernels. Instead of checking the kernel version in the Makefile for the corresponding broken driver, move the kernel version checking to the top-level Makefile and add CONFIG definitions that can be used the various Makefiles. This is also needed for working with 3rd party Linux kernels that may have upstream backports and need to set these CONFIG variables for their Linux kernel.
