Aleksandar Gerasimovski c435e63530 phy: mvebu-cp110-utmi: fix dr_mode property read from dts ...

[ Upstream commit e2ce913452 ]

The problem with the current implementation is that it does not consider
that the USB controller can have multiple PHY handles with different
arguments count, as for example we have in our cn9131 based platform:
"phys = <&cp0_comphy1 0>, <&cp0_utmi0>;".

In such case calling "of_usb_get_dr_mode_by_phy" with -1 (no phy-cells)
leads to not proper phy detection, taking the "marvell,cp110-utmi-phy"
dts definition we can call the "of_usb_get_dr_mode_by_phy" with 0
(#phy-cells = <0>) and safely look for that phy.
