ARM: pxa: Add non device-tree timer link to clocksource

As clocksource pxa_timer was moved to clocksource framework, the pxa_timer initialization needs to be a bit amended, to pass the necessary informations to clocksource, ie : - the timer interrupt (mach specific) - the timer registers base (ditto) - the timer clockrate Signed-off-by: Robert Jarzmik <[email protected]> Signed-off-by: Daniel Lezcano <[email protected]>
