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
