From: Quentin Schulz <quentin.sch...@theobroma-systems.com>
Long are gone the times TF-A couldn't handle the FDT passed by U-Boot.
Specifically, since commit e7b586987c0a ("rockchip: don't crash if we
get an FDT we can't parse") in TF-A, failure to parse the FDT will use
the fallback mechanism. This patch was merged in TF-A v2.4-rc0 from two
years ago.
Therefore, let's finally pass the FDT to TF-A so that it can get the
serial configuration from U-Boot FDT instead of requiring the user to
patch TF-A hardcoded fallback values.

rockchip: rk3399: pass platform parameter to TF-A
Finally pass the FDT address to TF-A since it now gracefully fallbacks to
hardcoded defaults if it cannot parse it. This allows us to avoid modifying
hardcoded values in TF-A to enable the console.
This was tested with TF-A v2.7.0 on Puma Haikou RK3399.
