USB: ehci-msm2: Put data lines into nondriving mode before PHY lpm

On some platforms, 2nd host controller is used to connect UICC card and
it applies pull down resistors on data lines. UICC card is full speed
ICUSB peripheral, which doesn't expect pull down resistor applied on
data lines by host. Hence put datalines in non driving mode during bus
suspend before putting PHY in low power mode so that pull downs will
be removed to save power.
