Amlogic T7 is an advanced application processor designed for smart display.

Add basic support for the T7 based Amlogic AN400 board, which describes
the following components: CPU, GIC, IRQ, Timer, UART. It's capable of
booting up into the serial console.
Few nits.
Is it possible to be more specific about it?

Please, don't put status in the middle of properties...
Will put status in the end of properties in next version.
