	xHCI misc cleanup patches for 3.10

	Hi Greg,

	Here's three cleanup patches for 3.10.  Nothing big here, just some debugging
	output changes, a macro rename, and a math macro change that should have no
	behavioral effects.

	Tested on the Intel Panther Point xHCI host, with USB storage and mouse, with
	xHCI debugging turned on.  I don't have the TI host that causes the debugging
	output changes to trigger.
