pcu_l1_if: move direct phy l1if functions to dedicated header file
The function headers for the direct phy related functions (l1if_...) are
currently directly listed in pcu_l1_if.cpp and osmobts_sock.c. Those
functions are basically the API interface definition between the
platform independed PCU code and the platform dependant direct phy code.
Lets put them into a dedicated header file.
