[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
