powerpc/km8360: fix the ODT parameters for CS0

The ODT parameters for km8360 set the ODT_WR_ACS bit in u-boot KM-2011.09
that is used in the release bootpackage for kmcoge5ne. During the
transition from the kmeter1 to km8360 this was changed to
ODT_RD_ONLY_CURRENT, which is uncorrect and causes faulty RAM accesses at
low temperatures.

This is now changed to ODT_WR_ONLY_CURRENT which is the equivalent of
ODT_WR_ACS.
