arm64: dts: qcom: ipq6018: improve pcie phy pcs reg table

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.
