[PATCH 2/4] Revert "usb: musb: da8xx: Set phy in OTG mode by default"

[Bastien Curutchet <bastien.curutchet@bootlin.com>]

This reverts commit 7ccf62941a38701ec9a42b4a0fa2868af456e96a.

da8xx_musb_set_mode() forces OTG mode regardless the selected mode even
if the property 'dr_mode = "host"' is present in device-tree. This
causes an unrecoverable error when VBUS supply is shut down : plugged
gadgets are no longer detected once VBUS supply is back.

Reverting it allows to have a selected mode coherent with device-tree's
description. IMO, this shouldn't cause regression because OTG mode is
the default selection when 'dr_mode' property is not set.
