Add support for the second SDMMC device.
The second SDMMC device was already supported but
the clock was never enabled. This fixes that.
sixlowpan: Preserve big-endian (network order) when uncompressing address.
This change is the counterpart to another recent endianness fix that occurred on compression of the ip address.

Photon rgbled fix
* configs/photon: Simplifies RGB led start-up logic.
* configs/photon: RGB led on Photon is common anode. CONFIGS_RGBLED_INVERT is now enabled

rgbled: Fixes led issues caused by uninitialized memory with CONFIG_RGBLED_MULTICHAN.
The uninitialized pwm_info_s struct caused a rogue channel to be started causing errros in the pwm driver

In connection-mode UDP sockets, a remote address is retained in the UDP connection structure. This determines both there send() will send the packets and which packets recv() will accept.
This same mechanism is used for connection-less UDP sendto: A temporary remote address is written into the connection structure to support the sendto() operation. That address persists until the next recvfrom() when it is reset to accept any address.
When UDP read-ahead buffering is enabled, however, that means that the old, invalid remote address can be left in the connection structure for some time. This can cause read-ahead buffer to fail, dropping UDP packets.
Shortening the time between when he remote address is reset (i.e., immediately after the sendto() completes) is not a solution, that does not eliminate the race condition; in only makes it smaller.
With this change, a flag was added to the connection structure to indicate if the UDP socket is in connection mode or if it is connection-less. This change effects only UDP receive operations: The remote address in the UDP connection is always ignored if the UDP socket is not in connection-mode.
No for connection-mode sockets, that remote address behaves as before. But for connection-less sockets, it is only used by sendto().
