[PATCH v4 3/3] arm64: dts: amlogic: add support for Orbbec Zora P1

The Orbbec Zora P1 is an A311D (Meson G12B) board with 2/4 GiB DDR4,
an Ampak AP6256 combo module (Broadcom BCM43456 Wi-Fi over SDIO and
BCM4345C5 Bluetooth over UART_A).

According to the original Linux dts, the board is a modded version
of the ODROID-N2, with Amlogic A311D instead of the original S922X
and WiFi and Bluetooth support.
So the device tree builds on meson-g12b-a311d.dtsi and
meson-g12b-odroid-n2.dtsi (using same vddcpu values of N2+),
extended with the board-specific GPIO wiring for the AP6256 handling,
and some modifications for the led, GPIO_ACTIVE_LOW instead of
GPIO_ACTIVE_HIGH and different label (it is a green led, not blue as
in the Odroid N2).
Add the new DTB to the Makefile.
