    vboot2: tpm2 factory initialization.
    
    This patch adds a TPM2 specific path in the vboot2 initialization
    sequence when the device is turned on in the factory for the first
    time, namely two secure NVRAM spaces are created, with different
    access privileges.
    
    The higher privilege space can be modified only be the RO firmware,
    and the lower privilege space can be modified by both RO and RW
    firmware.
    
    The API is being modified to hide the TPM implementation details from
    the caller.
    
    Some functions previously exported as global are in fact not used
    anywhere else, they are being defined static.
    
    BRANCH=none
    BUG=chrome-os-partner:50645
    TEST=when this code is enabled the two secure spaces are successfully
         created during factory initialization.

    squashed:
    
    mock tpm: drop unused functions
    
    safe_write() and safe_define_space() functions are defined in
    secdata_mock.c, but not used in mocked TPM mode.
    
    The actual functions have been redefined as static recently and their
    declarations were removed from src/include/antirollback.h, which now
    causes compilation problems when CONFIG_VBOOT2_MOCK_SECDATA is
    defined.
    
    Dropping the functions from secdata_mock.c solves the problem.
    
    BRANCH=none
    BUG=none
    TEST=compilation in mock secdata mode does not fail any more.
