[FIX PATCH] powerpc/pseries: Fix vector5 in ibm architecture vector table

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)

Applied to powerpc fixes, thanks.
