[meta-rockchip] add support for PX30 SoC

From: Quentin Schulz <quentin.schulz@theobroma-systems.com>

Rockchip PX30 SoC is a quad-core ARM Cortex-A35 CPU fully implementing
the ARMv8-A instruction set with ARM Neon Advanced SIMD and Cryptography
Extensions.

This adds a base configuration file which can be included by PX30-based
boards and the required changes in U-Boot and TF-A for proper support.

Applied to meta-rockchip, both master and kirkstone branches.
Thanks!
