driver/it83xx: change Rd_DB to Rd_5.1k in EC hibernate
We change Rd_DB to Rd_5.1k in EC hibernate. HW auto asserts Rd_DB
on CCs when EC is power off.
BUG=none
BRANCH=none
TEST=on board reef_it8320 and it8320_evb, in EC hibernate mode:
1.can wakeup by AC plug in, then pd state to SNK_READY.
2.Rd_5.1k power consumption is more 1uA than Rd_DB.
