No, they are generic to any tis phy that implements read only through
read_bytes.
(Honestly, I'm not sure we made the best choice here having phy
functions for all the versions, we are not that performance
sensitive, just getting rid of everything but read_bytes from the
phy_ops would probably also be a reasonable thing to do.)
