Arnd Bergmann 26dbffb2a4 drm/stm: add COMMON_CLK dependency 
The added lvds driver and a change in the dsi driver resulted in failed
builds when COMMON_CLK is disabled:

x86_64-linux-ld: drivers/gpu/drm/stm/dw_mipi_dsi-stm.o: in function `dw_mipi_dsi_stm_remove':
dw_mipi_dsi-stm.c:(.text+0x51e): undefined reference to `clk_hw_unregister'

x86_64-linux-ld: drivers/gpu/drm/stm/lvds.o: in function `lvds_remove':
lvds.c:(.text+0xe3): undefined reference to `of_clk_del_provider'
x86_64-linux-ld: lvds.c:(.text+0xec): undefined reference to `clk_hw_unregister'
x86_64-linux-ld: drivers/gpu/drm/stm/lvds.o: in function `lvds_pll_config':

x86_64-linux-ld: drivers/gpu/drm/stm/lvds.o: in function `lvds_probe':

x86_64-linux-ld: lvds.c:(.text+0x148b): undefined reference to `of_clk_hw_simple_get'
x86_64-linux-ld: lvds.c:(.text+0x1493): undefined reference to `of_clk_add_hw_provider'
x86_64-linux-ld: lvds.c:(.text+0x1535): undefined reference to `clk_hw_unregister'

Add this as a dependency for the stm driver itself, since it will be
required in practice anyway.
