arm64: dts: lx2160a: add lx2160acex7 device tree

The device tree enables the following features -
1. dpmac17 RGMII MAC connected to Atheros AR8035 phy
2. 2x MDIO busses
3. 2x USB 3.0 controllers
4. 4x SATA ports
5. MT35X 512Mb SPI flash
6. Temperature sensor on i2c0 channel 3
7. AMC6821 temperature and PWM fan controller

The module supports AMC6821 and EMC2301 PWM controllers where either can
be assembled, but not both together since the PWM and TACH signals are
shared between them.
