fix go-gorm/gorm#6033

User Case Description

type Test struct {
    Date time.Time `gorm:"type:date"`
    Time time.Time `gorm:"type:time"`
    DefaultDateTime time.Time
}

CREATE TABLE `tests` (`date` date,`time` time,`default_date_time` datetime)

Not only time, but actually all types have the same problem, can we skip to getSchemaCustomType, if the tag type is specified without specifying precision, size?
If so, we only need to add a field in schema.Field to identify it

go-gorm/sqlserver#86

So, we need to create a new tag in gorm and then upgrade dirver's dependence?
