iomap.h defines the base address of Tegra peripherals. Most of this information comes from device tree now, and hence can be deleted. Entries are kept for various system peripherals that low-level code (such as initial boot, system suspend/resume, debug) still requires. Removing the values removes the temptation for someone to use them. Signed-off-by: Stephen Warren <swarren@nvidia.com>
