mb/emulation/qemu-q35: Enable option for TPM
This enables the mainboard to use a TPM if it is selected in the
configuration. By default this does nothing, but it allows the
TPM to be enabled and used with the CONFIG_USER_TPM2 Kconfig option.
Using a TPM with QEMU requires either a physical TPM backend or
the swtpm package with a socket:
-chardev socket,id=swtpm,path=/tmp/swtpm/socket
-tpmdev emulator,id=tpm0,chardev=swtpm
-device tpm-tis,tpmdev=tpm0
