This patchset is split off the "Add TH1520 USB support" patchset,
dedicating to enable the IO expansion chips, because the situation
becomes complex when one of them (but not all) was added for Wi-Fi
support.

I fixed a small issue of the existing I2C1 device node, and then all
original patches are aligned with the existing I2C1 node for
consistency.
