This change adds infrastructure to automatically generate the physBase macro, the avail_p_regs array, and the dev_p_regs array based on a device tree. Platforms can opt-in to using this by adding DTS files to the KernelDTSList variable. The Python script uses the hardware.yml file to determine which devices in the device tree are of interest to the kernel and should be hidden from userspace and instead mapped into the kernel. Note that currently the kernel mappings are not (yet) generated, however most of the infrastructure needed to make that happen is present.
