rockchip: Use coreboot-supplied serial console on coreboot systems
This patch changes all Rockchip platforms to initialize the serial console with information supplied by coreboot rather than hardcoded base address and divisor values if BL31 is run on top of coreboot. Moving the BL2-to-BL31 parameter parsing as early as possible to ensure that the console is available for all following code. Also update the Rockchip platform to use MULTI_CONSOLE_API.
