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).

TEST=Booted on Pinky.
