perf list: fix short description for some cache events

Correct the short description of the following events:
DCW_REQ, DCW_REQ_CHIP_HIT, DCW_REQ_DRAWER_HIT, DCW_REQ_IV,
DCW_ON_CHIP, DCW_ON_CHIP_IV, DCW_ON_CHIP_CHIP_HIT,
DCW_ON_CHIP_DRAWER_HIT, CW_ON_MODULE, DCW_ON_DRAWER,
DCW_OFF_DRAWER, IDCW_ON_MODULE_IV, IDCW_ON_MODULE_CHIP_HIT,
IDCW_ON_MODULE_DRAWER_HIT, IDCW_ON_DRAWER_IV, IDCW_ON_DRAWER_CHIP_HIT,
IDCW_ON_DRAWER_DRAWER_HIT, IDCW_OFF_DRAWER_IV, IDCW_OFF_DRAWER_CHIP_HIT,
IDCW_OFF_DRAWER_DRAWER_HIT, ICW_REQ, ICW_REQ_IV, CW_REQ_CHIP_HIT,
ICW_REQ_DRAWER_HIT, ICW_ON_CHIP, ICW_ON_CHIP_IV, ICW_ON_CHIP_CHIP_HIT,
ICW_ON_CHIP_DRAWER_HIT, ICW_ON_MODULE and ICW_OFF_DRAWER.

The second Cache should be L2-Cache.

Output before (display diff of the first four events)
  # perf list -d
  DCW_REQ
       [Directory Write Level 1 Data Cache from Cache. Unit: cpum_cf]
  DCW_REQ_CHIP_HIT
       [Directory Write Level 1 Data Cache from Cache with Chip HP \
	       Hit. Unit: cpum_cf]
  DCW_REQ_DRAWER_HIT
       [Directory Write Level 1 Data Cache from Cache with Drawer \
	       HP Hit. Unit: cpum_cf]
  DCW_REQ_IV
       [Directory Write Level 1 Data Cache from Cache with Intervention. \
	       Unit: cpum_cf]

Output after:
  # perf list -d
  DCW_REQ
       [Directory Write Level 1 Data Cache from L2-Cache. Unit: cpum_cf]
  DCW_REQ_CHIP_HIT
       [Directory Write Level 1 Data Cache from L2-Cache with Chip HP \
	       Hit. Unit: cpum_cf]
  DCW_REQ_DRAWER_HIT
       [Directory Write Level 1 Data Cache from L2-Cache with Drawer \
	       HP Hit. Unit: cpum_cf]
  DCW_REQ_IV
       [Directory Write Level 1 Data Cache from L2-Cache with \
	       Intervention. Unit: cpum_cf]
