ARM: dts: msm: eud: Do not vote for the clocks by default

It's expected that the EUD clock, GCC_USB_PHY_CFG_AHB2PHY_BCR,
is enabled by the bootloader and there's no reason for the
driver to explicitly cast a vote on it. Moreover, this clock
is binded with the reset framework's clock, GCC_GP1_CLK_SRC.
Hence, explicitly enabling GCC_USB_PHY_CFG_AHB2PHY_BCR would
also enable GCC_GP1_CLK_SRC and it would not be managed
properly. Hence, do not vote for GCC_USB_PHY_CFG_AHB2PHY_BCR
explicitly.
