usb: fotg210: fix OTG-only build
The fotg210 module combines the HCD and OTG drivers, which then
fails to build when only the USB gadget support is enabled
in the kernel but host support is not:
aarch64-linux-ld: drivers/usb/fotg210/fotg210-core.o: in function `fotg210_init':
fotg210-core.c:(.init.text+0xc): undefined reference to `usb_disabled'
Move the check for usb_disabled() after the check for the HCD module,
and let the OTG driver still be probed in this configuration.
A nicer approach might be to have the common portion built as a
library module, with the two platform other files registering
their own platform_driver instances separately.
