i40e: Remove unused i40e_(read|write)_phy_register

Browse Source 
i40e_read_phy_register() and i40e_write_phy_register() were added in
2016 by
commit f62ba91458 ("i40e: Add functions which apply correct PHY access
method for read and write operation")

but haven't been used.

Remove them.

(There are more specific _clause* variants of these functions
that are still used.)
