[PATCH 1/2] phy: qcom-qmp-pcie: split pcs_misc init cfg for ipq8074 pcs table

From: Christian Marangi
Date: Thu Nov 03 2022 - 17:22:00 EST


Commit af6643242d3a ("phy: qcom-qmp-pcie: split pcs_misc region for ipq6018
pcie gen3") reworked the pcs regs values and removed the 0x400 offset
for each pcs_misc regs.

This change caused the malfunction of ipq8074 downstream since it still
has the legacy pcs table where pcs_misc are not placed on a different
table and instead put together assuming the offset of 0x400 for the
related pcs_misc regs.

Split pcs_misc init cfg from the ipq8074 pcs init table to be handled
correctly to prepare for actual support for gen3 pcie for ipq8074.
