Subject: [PATCH] drm/kmb: remove unused set_test_mode_src_osc_freq_target_low,hi_bits functions

clang with W=1 reports
drivers/gpu/drm/kmb/kmb_dsi.c:822:2: error: unused function
'set_test_mode_src_osc_freq_target_low_bits' [-Werror,-Wunused-function]
set_test_mode_src_osc_freq_target_low_bits(struct kmb_dsi *kmb_dsi,
^
drivers/gpu/drm/kmb/kmb_dsi.c:834:2: error: unused function
'set_test_mode_src_osc_freq_target_hi_bits' [-Werror,-Wunused-function]
set_test_mode_src_osc_freq_target_hi_bits(struct kmb_dsi *kmb_dsi,
^
These static functions are not used, so remove them.
