[PATCH] ARM: davinci: convert to clockevents_config_and_register

[Uwe Kleine-König]

clockevents_config_and_register is superior compared to setting
shift/mult and {min,max}_delta_ns by hand.

Hello,

I wonder where the 50 us limit comes from. This is not a hardware limit,
is it?

Best regards
Uwe
