From: Aidan <[email protected]> Add a TPM 2.0 TIS MMIO node at the address QEMU's virt machine exposes when started with -device tpm-tis-device. This lets the in-tree QEMU+swtpm test path (used by the wolfTPM Python test suite, and similarly usable by anyone bringing up the existing TPM 2.0 stack against swtpm) work without having to inject a DT overlay at runtime.
Address 0x0c000000 / size 0x5000 matches QEMU's virt machine TPM TIS region.
