Add the "orbbec" vendor prefix for Orbbec Inc., a manufacturer of
3D depth cameras and embedded vision boards. The prefix is needed by
an upcoming board compatible string ("orbbec,zora-p1") introduced by
this series.

Document the "orbbec,zora-p1" compatible for the Orbbec Zora P1 board,
which is based on the Amlogic A311D (Meson G12B) SoC. The corresponding
device tree is added in the follow-up patch.
The "orbbec" vendor prefix used here is added in the first patch of this
series

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), HDMI audio output.
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 "orbbec,zora-p1" compatible to the amlogic.yaml board binding
(the "orbbec" vendor prefix is already registered) and the new DTB to
the Makefile.
