panda: fix crash when not using barebox as second stage
If barebox is not used as the MLO, then it crashes during boot
with the below error message:

This is because the USBHOST module is not enabled. The module enable
is is normally done in mach-omap/xload.c which never gets called.
Since we're configuring the USBHOST CLKCTRL register in the board file
anyway, we might as well explicitly enable the module in the same place.
