[ARM] tegra: harmony: Add harmony board file
v2: fixes from Russell King - include linux/io.h instead of mach/io.h v3: fixes from Linus Walleij - remove /16 * 16 from UART clock v3: - Fix checkpatch issues - make board init calls explicit - use clock init table to set clocks - remove panel Signed-off-by: Colin Cross <ccross@android.com> Signed-off-by: Erik Gilling <konkers@android.com>
