media: bcm2835-unicam: Depend on COMMON_CLK

The bcm2835-unicam driver calls the clk_set_min_rate() function, which
is declared but not implemented on platforms that don't provide
COMMON_CLK. This causes linkage failures with some configurations.

Fix it by depending on COMMON_CLK. This only slightly restricts
compilation testing, but not usage of the driver as all platforms on
which the hardware can be found provide COMMON_CLK.
