Subject: [PATCH v2 05/14] phy: qcom-qmp-pcie-msm8996: drop unused in-layout configuration

The MSM8996 QMP PCIe PHY driver no longer uses the "in-layout"
configuration macro to configure registers that are typically accessed
using "regs_layout" arrays (e.g. QPHY_START_CTRL) so drop this unused
feature.
