[PATCH 2/6] arm64: dts: qcom: sm8250: Commonize PCIe pins

[Konrad Dybcio]

Commonize PCIe pins, along with pin definitions for PCIe-connected
MHI modem (not enabled by default, as it's useless on modem-less boards).

While at it, remove "output-low" from the RB5 board, as it's
not necessary - we already explicitly pull the perst pin low.
