If CONFIG(CRB_TPM) is enabled but the TPM is inactive, and no other TPM
interface (SPI, I2C, Memory-Mapped) is configured, the function would
incorrectly fallback to generate a TPM2 table for FIFO mode.
This commit adds a check to ensure crb_tpm_is_active() is only
called if CONFIG(CRB_TPM) is enabled and no other TPM interface
is present. If the CRB TPM is inactive and no other TPMs are
available, the function now exits early to prevent generating
an invalid TPM2 table.
Test=boot `starlabs/starlite_adl` and check Linux doesn't probe for a
TPM when PTT is not active.
