[PATCH] arm64: dts: qcom: shikra: Enable dTPM on EVK boards

[Khalid Faisal Ansari]

The Shikra EVK boards (CQM, CQS, IQS) carry an ST33 discrete TPM
connected via SPI5. Enable the SPI controller and add the TPM node
with the ST33HTPM compatible and a 20 MHz max clock.

The Shikra EVK boards (CQM, CQS, IQS) have an ST33 discrete TPM (dTPM)
connected over SPI5. Enable the SPI controller and add the TPM node for
all three board variants.

This series depends on the SPI5 node addition in shikra-evk.dtsi:
