The DRC index pointer us updated on an OPCODE_ADD, but never
actually read.  Remove the used pointer and shift up OPCODE_ADD
to group with OPCODE_DELETE which also provides a noop.

Fixes the following W=1 kernel build warning:

 drivers/misc/cxl/flash.c: In function ‘update_devicetree’:
 drivers/misc/cxl/flash.c:178:16: warning: variable ‘drc_index’ set but not 
used [-Wunused-but-set-variable]
 178 | __be32 *data, drc_index, phandle;
 | ^~~~~~~~~
