V4L/DVB (11061): au8522: move shared state and common functions into a separate header files
Move the au8522 state structure, as well as exposing functions needed by the
analog side of the demodulator into a common header file.
Thanks to Michael Krufky <mkrufky@linuxtv.org> and Steven Toth
<stoth@linuxtv.org> for providing sample hardware, engineering level support,
and testing.
