[PATCH] drm/kmb: Remove set_test_mode_src_osc_freq_target_{hi,low}_bits()

[PATCH] drm/kmb: Remove set_test_mode_src_osc_freq_target_{hi,low}_bits()

[Nathan Chancellor]

clang with W=1 warns:

drivers/gpu/drm/kmb/kmb_dsi.c:812:2: 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:824:2: error: unused function

        set_test_mode_src_osc_freq_target_hi_bits(struct kmb_dsi *kmb_dsi,
        ^
2 errors generated.

Remove them, as they have been unused since the driver's introduction in
commit 98521f4d4b4c ("drm/kmb: Mipi DSI part of the display driver").
