ima: Fix Kconfig to select TPM 2.0 CRB interface
TPM_CRB driver provides TPM CRB 2.0 support. If it is built as a module, the TPM chip is registered after IMA init. tpm_pcr_read() in IMA fails and displays the following message even though eventually there is a TPM chip on the system. ima: No TPM chip found, activating TPM-bypass! (rc=-19) Fix IMA Kconfig to select TPM_CRB so TPM_CRB driver is built in the kernel and initializes before IMA.
