[hw,sysrst_ctrl] Update bounds for expected_wakeup counter

For cases where, (ac/pwrb/lid)_cycles = get_(ac/pwrb/lid)_timer + 2,ULP test sequence doesnt not
update exp_z3_wakeup, because `i` value starts from 0 which itself indicates one cycle of
transition/change in input level

Update bound value to fix this issue
