arm: MediaTek: add basic support for MT7623 boards

This adds a general board file based on MT7623 SoCs from MediaTek.

As this u-boot is loaded by MTK proprietary preloader, there is no
low level initializtion codes.

The MediaTek MT7623 is a ARM-based SoC with a quad-core Cortex-A7
including NEON and GPU, Mali-450 graphics, several DDR3 options,
crypto engine, built-in Wi-Fi / Bluetooth combo chip, JPEG decoder,
video interfaces supporting HDMI and MIPI, and video codec support.
Peripherals include Gigabit Ethernet, switch, USB3.0 and OTG, PCIe,
I2S, PCM, S/PDIF, UART, SPI, I2C, IR TX/RX, and PWM.
