Generalize some qca808x LED functions in preparation for qca807x LED support. The LED implementation of qca808x and qca807x is the same but qca807x supports also Fiber port and have different hw control bits for Fiber port. To limit code duplication introduce micro functions that takes reg instead of LED index to tweak all the supported LED modes. Also move to shared header all the common LED bits.
