Why this driver is not developed through MFD architecture then? nuvoTon chip
looks like multi-function chip, isn't it?

It is, in the sense that it does multiple things.  But, for this
particular device, it makes the keyboard available as an i2c device.
I don't see any particular reason to tie that to other functionality
that the chip provides.
