Summary:                    [patch] external timing source
Description: 
This patch adds support for getting a 1khz clock from external modules. The
first implementation which provides this external clock is done in mISDN
(hfcmulti). 

The hfc multi chip has a 1khz timing interrupt which is very accurate and
can be driven by the pstn, if the system has no zaptel card in it it makes
sense to use the interrupt from the hfc chip. 

ztdummy uses RTC if available in the first place, when the hfcmulti driver
is loaded it registers at ztdummy and changes the timing source.

The patch probably does not apply to ztdummy after the changes to add hires
timers.

In addition it should support the hires times case, not only the RTC
case.

It should also probably set the desc(ription) of the span to note the
different clock source.
