phy: cdns-dphy: Store hs_clk_rate and return it

Browse source

[ Upstream commit 689a54acb5 ]

The DPHY driver does not return the actual hs_clk_rate, so the DSI
driver has no idea what clock was actually achieved. Set the realized
hs_clk_rate to the opts struct, so that the DSI driver gets it back.
