Subject: [PATCH 3/3] misc: cxl: flash: Remove unused variable 'drc_index'

Keeping the pointer increment though.

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;
 | ^~~~~~~~~
