Renaming docs seems to be en vogue at the moment, so fix on of the
grossly misnamed directories. We usually never use "virtual" as
a shortcut for virtualization in the kernel, but always virt,
as seen in the virt/ top-level directory. Fix up the documentation
to match that.

Hi,
This is the V15 of my Ingenic TCU patchet.
The big change since V14 is that the custom MFD driver

The patchset was based on mips/mips-next, but all of them minus
