[PATCH] isdn: work around excessive udelay()
As reported in http://bugzilla.kernel.org/show_bug.cgi?id=6970, ISDN can issue excessively-long udelays, which triggers a build-time error on ARM. This is very sucky of ISDN, but I doubt if anyone is going to suddenly fix it. So change the macro to do the microsecond counting itself.
