This patch makes some cosmetic changes to dummy_hcd:

	Minor alterations of comments and whitespace.

	Replace USB_PORT_FEAT_xxx with USB_PORT_STAT_xxx.  This is
	appropriate as the values are stored in a status variable
	and they aren't feature indices.  Also it allows the
	elimination of a bunch of awkward bit shift operations.
