Subject: [PATCH] sun50i: a64: A64-Teres-I board detect builtin keyboard

A64-Teres-I board is a laptop which comes with a builtin keyboard.
The keyboard+trackpad controller pauses for 2 seconds at a firmware
prompt before loading its HID interface.

U-Boot needs to wait equally long to reliably enable the keyboard.
