USI control is now extracted to dedicated USIv2 driver. Remove USI
related code from serial driver to avoid conflicts and code duplication.

What conflicts?

There might be possible conflicts when accessing the same USI register
from both serial driver and USIv2 driver. Also there will be conflicts
when trying to access the same I/O address space in those both
drivers.

What duplication?  All you did here was delete code.

It's all explained in [PATCH 0/8], but long story short, I've added
USIv2 driver (in this series) which handles the code that's removed
from serial driver in this patch.
