To integrate tpm_event_log with IMA subsystem,
tpm_crb and tpm_crb_ffa driver should be built as built-in
(CONFIG_TCG_CRB=y && CONFIG_TCG_CRB_FFA=y).

However, this could make failure for ima_init() gets tpm chip when
each initcall function deployed like:

0000000000000888 l       .initcall6.init	0000000000000000 crb_acpi_driver_init
000000000000088c l       .initcall6.init	0000000000000000 tpm_crb_ffa_driver_init

The only failure I see is the patch 1/2 which changes init call level,
and leaves kernel Git to a broken state.

It breaks the famous "zero regressions policy".
