L2 RAW channel allows to use some functions of IP stack for RAW access
of network drivers. It is hidden from user and is selected by 2520 raw
driver.

Add TI CC2520 driver allowing RAW access to radio interface similar
way Bluetooth user channel works. This makes possible to handle radio
channel inside external 802.15.4 stacks, for example export it over USB
and handle in Linux.

Helper functions to read and write data across multiple fragments.
Write function always adds at the end of last fragment. If there is
no space in last fragment new data fragment will be created and added
to input buffer.
Read function start reading from offset of input fragment. If the
required data is located in mutliple fragments it reads from list
of fragments and returns position and fragment where read stopped.
Skip function start skipping from offset of input fragment. If the
required length is across multiple fragments it skip till length and
returns position and fragment where read stopped. This is useful
when reading with unwanted data (reserved or unhandled data).
These functions are quite useful when handling with multiple fragments.
