Modify the iProc MAINTAINER to cover the Nortstar Plus SoCs, and add me
to the list of people responsible for it.  Since iProc is a family of
SoCs that includes more than just Cygnus (i.e., Northstar (BCM5301X),
Northstar Plus, Northstar 2, and a number of other platforms), remove it
from the title to avoid any future confusion.
