[PATCH] phy: tegra: depend on COMMON_CLK to fix compile tests

[Krzysztof Kozlowski]

The Tegra USB PHY driver uses Common Clock Framework thus it cannot be
built on platforms without it (e.g. compile test on MIPS with RALINK and
SOC_RT305X):

    /usr/bin/mips-linux-gnu-ld: drivers/usb/phy/phy-tegra-usb.o: in function `tegra_usb_phy_init':
    phy-tegra-usb.c:(.text+0x1dd4): undefined reference to `clk_get_parent'
