[PATCH v1] arm64: dts: qcom: Add dmic45 support to rb3gen2 vision mezzanine overlay

[Kumar Anurag]

Add pinctrl states and VA macro routing for two additional digital
microphones (DMIC4/DMIC5) that are present on the vision mezzanine
add-on board, mirroring the dmic01/dmic23 pattern already used for
the on-board microphones.
