Subject: [PATCH] drm/kmb: Remove some unused functions

Functions set_test_mode_src_osc_freq_target_low_bits() and
set_test_mode_src_osc_freq_target_hi_bits() are defined in the kmb_dsi.c
file, but not called elsewhere, so remove these unused functions.

drivers/gpu/drm/kmb/kmb_dsi.c:822:2: warning: unused function 'set_test_mode_src_osc_freq_target_low_bits'.
drivers/gpu/drm/kmb/kmb_dsi.c:834:2: warning: unused function 'set_test_mode_src_osc_freq_target_hi_bits'.
