reset: intel: fix a compile warning about REG_OFFSET redefined 

kernel test robot reports a compile warning about REG_OFFSET redefined
in the reset-intel-gw.c after merging commit e44ab4e14d ("regmap:
Simplify implementation of the regmap_read_poll_timeout() macro"). the
warning is like that:

drivers/reset/reset-intel-gw.c:18:0: warning: "REG_OFFSET" redefined
 #define REG_OFFSET GENMASK(31, 16)
