USB: EHCI: make all debugging depend on CONFIG_DYNAMIC_DEBUG
The debugging facilities in ehci-dbg.c follow an uneven pattern. Some of them are protected by "#ifdef CONFIG_DYNAMIC_DEBUG" and some aren't, presumably in the hope of having some of the debugging output available in any configuration. This leads to build problems when dynamic debugging isn't configured. Rather than try to keep this complicated state of affairs, let's just make everything dependent on CONFIG_DYNAMIC_DEBUG.
