arm64: dts: mediatek: asurada: Add ChromeOS EC 

Add support for the ChromeOS Embedded Controller present on the Asurada
platform. It is connected through the SPI1 bus and offers several
functionalities: base detection, PWM controller, I2C tunneling,
regulators, Type-C connector management, keyboard and Smart Battery
Metrics (SBS).
