[K64F] Add mbed_mac_address implementation

[sg-]

Currently the MAC for K64 is hardcoded and causes conflicts when multiple devices are on the same network. Downside is that to override this from an application $Sub$$ and $Super$$ need to be used but this seems reasonable. Seems like mbed_mac_address should be weakly defined for all SDK ports rather than in the mbed_common

To understand the proposal, mbed_interface code file contains implementation for mbed_mac_address(). And you propose to move it to mbed_override code file , target specific implementation.

Can you elaborate on "Downside is that to override this from an application $Sub$$ and $Super$$ need to be used but this seems reasonable. " ?

The comment should be updated in the mbed_interface header file, shouldn't be?

/** This returns a unique 6-byte MAC address, based on the interface UID
 * If the interface is not present, it returns a default fixed MAC address (00:02:F7:F0:00:00)
 *
 * This is a weak function that can be overwritten if you want to provide your own mechanism to
 * provide a MAC address.
 *
 *  @param mac A 6-byte array to write the MAC address
 */
void mbed_mac_address(char *mac);

What should this be updated to? This is still a common file. I agree that
this implementation should change in general and each platform should
implement something that is semi-unique at the very least but there are
still a few platforms that use this a the default implementation namely the
Arch Pro, EA 4088 and MTS Gambit
