rk3288: Move UART initialization to bootblock_mainboard_early_init()
This patch uses the new bootblock_mainboard_early_init() hook to run the UART pinmuxing on rk3288-based boards before initializing the console. This allows us to get rid of the hacky second console_init() call in bootblock_soc_init(). We can also simplify the pinmux selection a bit since we know that a given board always uses the same UART (still keep an assert around to be sure, though). BRANCH=None BUG=chrome-os-partner:32123 TEST=Booted on Pinky.
