[PATCH] phy: qcom-qmp-pcie: correct sm8350 PHY tables

[Dmitry Baryshkov]

Correct sm8350 PCIe PHY tables according to the vendor dtsi file.
This accounts some additional differences between PHY programming on
sm8350 and sm8450.

The name for the PCS register 0x8 is not present in the vendor kernels,
but since on other generations the register prior to POWER_STATE_CONFIG2
is called POWER_STATE_CONFIG1, we can establish that as its name.

Fixes: c70052739d16 ("phy: qcom-qmp-pcie: add support for sm8350 platform")
