Compiling the saa7164 driver without CONFIG_VIDEO_ADV_DEBUG set triggers
these GCC warnings:
drivers/media/pci/saa7164/saa7164-encoder.c:1301:12: warning:
‘saa7164_g_register’ defined but not used [-Wunused-function]
drivers/media/pci/saa7164/saa7164-encoder.c:1314:12: warning:
‘saa7164_s_register’ defined but not used [-Wunused-function]
Silence these warnings by wrapping these two functions in an "#ifdef
CONFIG_VIDEO_ADV_DEBUG" and "#endif" pair.

0) Compile tested only.
1) These warnings are apparently a side effect of commit
5faf7db804e1e67ab8f78edb305d1858779a6279 ("[media] saa7164: get rid of
warning: no previous prototype"): now that these two functions are
static GCC can determine that they are unused in this case.
