[U-Boot] [PATCH 11/13] arm64: zynqmp: probe firmware driver

[Michal Simek]

From: Ibai Erkiaga <ibai.erkiaga-elorza at xilinx.com>

Probe ZynqMP firmware driver on the board initialization phase and
ensure that firmware is in place to continue execution. The probing is
done on board_init so it can be used for both SPL and U-Boot proper.
