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.
