arm64: dts: qcom: ipq6018: improve pcie phy pcs reg table
[ Upstream commit 08f399a818b0eff552b1f23c3171950a58aea78f ]
This is not a fix on its own but more a cleanup. Phy qmp pcie driver
currently have a workaround to handle pcs_misc not declared and add
0x400 offset to the pcs reg if pcs_misc is not declared.
Correctly declare pcs_misc reg and reduce PCS size to the common value
of 0x1f0 as done for every other qmp based pcie phy device.
