[PATCH v2] ARM: sunxi: Split the various SoCs support in Kconfig

[Maxime Ripard]

This will allow to better isolate various options, and reduce the overall
kernel size if we're interested in only one of the SoCs.

Changes from v1:
  - Changed from config to menuconfig
  - Enabled the SoCs variants by default if the machine is selected
