[media] b2c2: flexcop: avoid unused function warnings
The flexcop driver has two functions that are normally used, except
when multiple frontend drivers are disabled:
drivers/media/common/b2c2/flexcop-fe-tuner.c:42:12: warning: 'flexcop_set_voltage' defined but not used [-Wunused-function]
drivers/media/common/b2c2/flexcop-fe-tuner.c:71:12: warning: 'flexcop_sleep' defined but not used [-Wunused-function]
This avoids the build warning by updating the #ifdef for flexcop_set_voltage
to the exact condition under which it is used. For flexcop_sleep, the
condition is rather complex, so I resort to marking it as __maybe_unused,
so the compiler can silently drop it.
