Description of these functions can be removed when all drivers migrated
to the new API. Also implementation descriptions + examples would still
be needed AFAICT.

I diagreed - if we deprecated functions the only thing that should
be mentioned is a "don't use these". 

I will try to paraphrase myself. The new API deprecates pci_enable_msi*_range
functions, but I am not that sure about others. Certainly, pci_msi*_vec_count
and pci_enable_msi*_exact could have (and AFAIR do have) uses that can not be
covered by automatic initialization of pci_alloc_irq_vectors().
