This patch (as917) removes a now-unnecessary level of subroutine
nesting from hub.c.  Since usb_port_suspend() does nothing but call
hub_port_suspend(), and usb_port_resume() does nothing but call
hub_port_resume(), there's no reason to keep the routines separate.

Also included in the patch are a few cosmetic changes involving
whitespace and use of braces.
