rockchip: add reset or power off gpio configuration for rk3399 We add plat parameter structs to support BL2 to pass variable-length, variable-type parameters to BL31. The parameters are structured as a link list. During bl31 setup time, we travse the list to process each parameter. throuth this way, we can get the reset or power off gpio parameter, and do hardware control in BL31. This structure also can pass other parameter to BL31 in future.

plat/rockchip: Switch to use new common BL aux parameter library This patch changes all Rockchip platforms to use the new common BL aux parameter helpers. Since the parameter space is now cleanly split in generic and vendor-specific parameters and the COREBOOT_TABLE parameter is now generic, the parameter type number for that parameter has to change. Since it only affects coreboot which always builds TF as a submodule and includes its headers directly to get these constants, this should not cause any issues. In general, after this point, we should avoid changing already assigned parameter type numbers whenever possible.

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.
