Joel Rosiene / DMX-K46Z

An initial port to the FRDM-K46Z based on the the following: https://developer.mbed.org/users/okini3939/notebook/dmx512/

Dependents:   FRDM-Dowser

Fork of DMX by Suga koubou

Need to update the UART references to the K46Z. The KE02 Sub-Family Reference Manual provides us with the required information.

The modifications are wrapped with the target for the K46: For example, defined(TARGET_KL46Z)
