Allwinner A100 is a new SoC with Cortex-A53 cores, this commit adds
the basical DTSI file of it, including the clock, i2c, pins, sid, ths,
nmi, and UART support.

You should use the arm,cortex-a53 compatible here, arm,armv8 is for
software models.

The node name is supposed to be the class of the device, and the DT spec
defines a list of them already. eeprom would be better suited here.

Ideally, the nodes here should be ordered by alphabetical order (so ddr
before GPU).

Thanks!
