Subject: [PATCH 21/31] video: fbdev: sstfb: Mark 3 debug variables as __maybe_unused

These are only used if SST_DEBUG_FUNC is set.

Declare them under the same clause as their use.

Fixes the following W=1 kernel build warning(s):

 drivers/video/fbdev/sstfb.c: In function ‘sst_detect_ics’:
 drivers/video/fbdev/sstfb.c:934:26: warning: variable ‘n_clk1_b’ set but not used [-Wunused-but-set-variable]
 drivers/video/fbdev/sstfb.c:934:16: warning: variable ‘n_clk0_7’ set but not used [-Wunused-but-set-variable]
 drivers/video/fbdev/sstfb.c:934:6: warning: variable ‘n_clk0_1’ set but not used [-Wunused-but-set-variable]
