ARM: dts: qcom: add Alfa Network AP120C-AC

ALFA Network AP120C-AC is a dual-band ceiling AP, based on Qualcomm
IPQ4018 + QCA8075 platform.

Specification:

- Qualcomm IPQ4018 (717 MHz)
- 256 MB of RAM (DDR3)
- 16 MB (SPI NOR) + 128 or 512 MB (SPI NAND) of flash
- 2x Gbps Ethernet, with 802.3af PoE support in one port
- 2T2R 2.4/5 GHz (IPQ4018), with ext. FEMs (QFE1952, QFE1922)
- 3x U.FL connectors
- 1x 1.8 dBi (Bluetooth) and 2x 3/5 dBi dual-band (Wi-Fi) antennas
- Atmel/Microchip AT97SC3205T TPM module (I2C bus)
- TI CC2540 Bluetooth LE module (USB 2.0 bus)
- 1x button (reset)
- 1x USB 2.0
- DC jack for main power input (12 V)
- UART header available on PCB (2.0 mm pitch)

This adds DTS for both the generic and custom Bit edition for Sartura.
