Jarkko Sakkinen 72c82b6521 tpm: Re-enable TPM chip boostrapping non-tpm_tis TPM drivers ...

[ Upstream commit 0c8862de05 ]

TPM chip bootstrapping was removed from tpm_chip_register(), and it
was relocated to tpm_tis_core. This breaks all drivers which are not
based on tpm_tis because the chip will not get properly initialized.

Take the corrective steps:
1. Rename tpm_chip_startup() as tpm_chip_bootstrap() and make it one-shot.
2. Call tpm_chip_bootstrap() in tpm_chip_register(), which reverts the
   things  as tehy used to be.
