[PATCH] ARM pcm043: New NOR Flash CS0 values

[PATCH] ARM pcm043: New NOR Flash CS0 values

[Teresa Gámez]

Set new CS0 values for new NOR-Flashes (28F256P33BF).
These values also work with older flashes (28F256P33B).

Also removed unnecessary setup of CSO in the core_init call.

Applied for next. Shouldn't hurt to have this already in place when
the other cfi patch is ready.
