drm/sun4i: add COMMON_CLK dependency
The sun4i drm driver uses the clk-provider interfaces, which are not available
when CONFIG_COMMON_CLK is disabled:
drivers/gpu/drm/sun4i/sun4i_dotclock.c:19:16: error: field 'hw' has incomplete type
struct clk_hw hw;
In file included from ../include/asm-generic/bug.h:13:0,
from ../arch/arm/include/asm/bug.h:59,
from ../include/linux/bug.h:4,
from ../include/linux/io.h:23,
from ../include/linux/clk-provider.h:14,
from ../drivers/gpu/drm/sun4i/sun4i_dotclock.c:13:
drivers/gpu/drm/sun4i/sun4i_dotclock.c: In function 'hw_to_dclk':
include/linux/kernel.h:831:48: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
...
This adds a Kconfig dependency to prevent the driver from being enabled
in this case.
