A133 support

[Parthiban]

Hi All,

Am currently adding support for Allwinner A133 SoC based on A100. Based on the [1],
A100 and A133 uses same IP across. But there is no public available datasheet or
user manual for A100.

Should A100 kept as base and A133 dtsi needs to added on top or A133 can be duplicated
into a new devicetree?
