regulator: as3711: Fix valid min_uV/max_UV checking in as3711_bound_check
Below cases are supposed to be valid:
min_uV == max_uV == info->max_uV
min_uV == max_uV == rdev->desc->min_uV
Don't return -EINVAL for above cases.
This patch also includes below cleanups:
- Use rdev_get_drvdata(rdev) instead of rdev->reg_data.
- Remove unnecessary WARN_ON, it looks pointless.
