Subject: [PATCH] ARM: dts: qcom-sdx55: Fix the base address of PCIe PHY

While convering the binding to new format, serdes address specified in the
old binding was used as the base address. This causes a boot hang as the
driver tries to access memory region outside of the specified address. Fix
it!
