drivers/i2c/tpm: Make driver safe for use in x86 pre-ram

Use CAR accessors where needed for accessing static data.
    In some cases this required some minor restructuring to pass
    in a variable instead of use a global one.

For the tpm_vendor_init the structure no longer has useful
    defaults, which nobody was depending on anyway.  This now
    requires the caller to provide a non-zero address.

Tested by enabling I2C TPM on reef and compiling successfully.
