6lowpan: change naming for lowpan private data
This patch changes the naming for interface private data for lowpan
intefaces. The current private data scheme is:
-------------------------------------------------
| 6LoWPAN Generic | LinkLayer 6LoWPAN |
-------------------------------------------------
the current naming schemes are:
- 6LoWPAN Generic:
- lowpan_priv
- LinkLayer 6LoWPAN:
- BTLE
- lowpan_dev
- 802.15.4:
- lowpan_dev_info
the new naming scheme with this patch will be:
- 6LoWPAN Generic:
- lowpan_dev
- LinkLayer 6LoWPAN:
- BTLE
- lowpan_btle_dev
- 802.15.4:
- lowpan_802154_dev
