[PATCH] phy: allwinner: Make PHY_SUN6I_MIPI_DPHY depend on COMMON_CLK

[Tiezhu Yang]

When CONFIG_ARCH_SUNXI is not set but CONFIG_COMPILE_TEST=y,
CONFIG_HAVE_CLK=y, CONFIG_HAVE_LEGACY_CLK=y, there exists
the following build errors with CONFIG_PHY_SUN6I_MIPI_DPHY=y:

drivers/phy/allwinner/phy-sun6i-mipi-dphy.o: In function `sun6i_dphy_init':
phy-sun6i-mipi-dphy.c:(.text+0x320): undefined reference to `clk_set_rate_exclusive'
drivers/phy/allwinner/phy-sun6i-mipi-dphy.o: In function `sun6i_dphy_exit':
phy-sun6i-mipi-dphy.c:(.text+0x2c8): undefined reference to `clk_rate_exclusive_put'

clk_set_rate_exclusive() and clk_rate_exclusive_put() are defined
in drivers/clk/clk.c, this file is built under CONFIG_COMMON_CLK,
so in order to build drivers/phy/allwinner/phy-sun6i-mipi-dphy.c
successful used with various configs, CONFIG_PHY_SUN6I_MIPI_DPHY
should depend on CONFIG_COMMON_CLK.
