[PATCH] Replace use of GET_64BIT(prop, i) with of_read_number().

[Jon Loeliger]

Remove uses of hack GET_64BIT() property macro and use
the more general of_read_number() function from prom.h
as suggested by Milton.

Someone in 64-bit land please check this!
I have no board on which to test this.  Sorry.
