The current defconfigs are BIOS-specific which makes it difficult to maintain multiple defconfigs for boards running the same BIOS. This patch re-organizes the defconfigs to be board-specific. A command line option BOARD is introduced to specify a board on which the current build targets at. The original PLATFORM is kept for backward compatibility which redirects to apl-mrb and nuc6cayh for sbl and uefi, respectively. The getting started guide is also updated accordingly. v1 -> v2: * Rewrite 'up2' to 'UP2'.
