drivers in Allwinner are CLK and RESET drivers, now these
available for USB usage.

So switch sunxi USB use EHCI and OHCI Generic controllers.

This allows to disable the USB driver model in SPL because it checks
the CONFIG_SPL_DM_USB variable for SPL builds. Nothing changes for
regular non-SPL builds.

Common USB code is built whenever USB is enabled (in non-SPL builds).
The USB uclass is built whenever (SPL_)DM_USB is enabled. Both need to
be independent from CMD_USB.

This allows building the SPL without driver model for USB. Since
CONFIG_SPL_DM_USB is enabled if and only if CONFIG_DM_USB was enabled
before, this patch does not change the build behaviour.
