[v2,03/14] phy: qcom-qmp-combo: drop unused in-layout configuration

Commit Message

Johan Hovold Oct. 12, 2022, 8:12 a.m. UTC

The QMP combo PHY driver does not use 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.
