This adds the bare minimum code to support Tegra186, with UART and eMMC working. The empty gpio.h is required because <asm/gpio.h> includes it. A future cleanup round may be able to solve this for all Tegra generations at once. mach-tegra/Makefile is adjusted not to compile anything for Tegra186, but instead to defer everything to mach-tegra/tegra186/Makefile. This allows the SoC code to pick-and-choose which of the C files in the "common" mach-tegra/ directory to compile in based on the SoC's needs. Most of the code is not valid for Tegra186, and this approach removes the need for mach-tegra/Makefile to contain many SoC-specific ifdefs. This approach may be applied to all other Tegra SoCs in a future cleanup round. board186.c is introduced to replace board.c and board2.c. These files currently contain a slew of SoC- and board-specific code that is not valid for Tegra186. This approach avoids adding yet more ifdefs to those files. A future cleanup round may refactor most of board*.c into board-/ SoC-specific functions files thus allowing the top-level functions like board_init_early_f to be shared again.
