drm/dp: add drm_dp_phy_name() for getting DP PHY name
Add a helper for getting the DP PHY name. In the interest of caller
simplicity and to avoid allocations and passing in of buffers, duplicate
the const strings to return. It's a minor penalty to pay for simplicity
in all the call sites.
v2: Rebase, add kernel-doc, ensure non-NULL always
