[PATCH v3] arm64: dts: qcom: hamoa-iot-evk: Enable TPM (ST33) on SPI11

[Khalid Faisal Ansari]

Enable ST33HTPM TPM over SPI11 on the Hamoa IoT EVK by adding the
required SPI and TPM nodes.

Signed-off-by: Khalid Faisal Ansari <khalid.ansari@oss.qualcomm.com>

Testing:
- TPM detected via tpm_tis_spi
- Verified functionality using tpm2-tools (e.g. tpm2_getrandom, tpm2_rsadecrypt)

Depends on:
