[U-Boot] [PATCH v2 12/14] arm: am33xx: Register USB controllers if DM_USB is used but not OF_CONTROL

[Jean-Jacques Hiblot]

When DM_USB is used, either the USB controllers are bound when the DTB
is parsed (when OF_CONTROL is enabled) or they are bound using the
U_BOOT_DEVICES() macro.
In the later case, the platform data is passed in a struct ti_musb_platdata
because it cannot be read from the DTB.

Changes in v2:
- simplify #ifdef trickery thanks to the new SPL_DM_USB option
