This patch doesn't change the original behavior, just change the name of the 
function,  so there is no regression.
I would suggest there is another bug in those drivers/devices that is 
orthogonal to this refactoring and should not block this from merging.
According to what you say  it can call just tpm_calc_oridnal_duration() instead 
of tpm1_calc_ordinal_duration(chip, ordinal),
but I prefer that someone that has those devices will do that change on top of 
this series as  I cannot test it.

Thanks
Tomas
