phy: ufs-qcom: disable RX LineCfg

Some UFS devices send incorrect LineCfg data as part of power mode change
sequence which may cause host PHY to go into bad state. Currently we
workaround this issue by disabling the device's TX LCC but disabling TX
LCC is much more complicated if both host and device supports UniPro 1.6
specification. To simplify the workaround, this change disables the host
PHY's RX LineCfg to skip processing incorrect LineCfg from device.
