[PATCH v2 30/30] misc: cxl: flash: Remove unused pointer

[Lee Jones]

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