This patch doesn't enable USB2.0 Host channel 0 because it is connected
to MAX3355 and cannot control the SHDN pin for now.

sh-pfc e6060000.pfc: function 'usb' not supported
sh-pfc e6060000.pfc: invalid function usb in map table

As the usb patches for pfc-r8a7795 haven't been posted yet, it's difficult
to test/comment.

Note that the functions were called "usb%u" in a previous version, and in the
pfc-r8a7795 code in the BSP.

Can you please post the pfc-r8a7795 patches, too?

Thanks!
