Subject: [PATCH 05/10] dt-bindings: phy: qcom,uniphy-pcie: Add ipq5332 bindings

Qualcomm IPQ5332 has single-lane and dual-lane PCIe UNIPHY
with Gen 3 support. This UNIPHY is similar to the one found
on Qualcomm IPQ5018. Hence add the bindings in qcom,uniphy-pcie.

Clocks and resets are different for IPQ5332. Update the
bindings to support both IPQ5018 and IPQ5332.

This patch depends on the below series which adds PCIe support in
Qualcomm IPQ5018
