pi3usb9201: Add always powered flag
In some designs, the PI3USB9201 is always powered whereas in other
designs it was assumed to be tied to a 5V rail that could be
controlled.
This commit simply adds a flag, PI3USB9201_ALWAYS_POWERED that a board
can use.
BUG=b:151688130, b:150814620
BRANCH=None
TEST=Enable on waddledoo, build and flash, verify that Type-A ports
are not powered when a charger is plugged in in S5/G3.
