With ibm,dynamic-memory-v2 and ibm,drc-info coming around the
same time, byte22 in vector5 of ibm architecture vector table
got set twice separately. The end result is that guest kernel
isn't advertising support for ibm,dynamic-memory-v2.
Fix this by removing the duplicate assignment of byte22.
Fixes: 02ef6dd8109b5 (powerpc: Enable support for ibm,drc-info devtree property)
Fixes: c7a3275e0f9e4 (powerpc/pseries: Revert support for ibm,drc-info devtree property)
