the davinci will need to use the __raw_writel/readl instead of this REG

coud you explain a few more?

as all davinic use the same lds regroup it will be better as done for the at91
and in preparation for the ompa3

please do not do it I'll update the mach-types myself
please send a linux sync request and specify against which arm kernel version
