usb: ohci-omap: avoid unused-variable warning
The dead code removal has led to 'need_transceiver' not being
used at all when OTG support is disabled:
drivers/usb/host/ohci-omap.c: In function 'ohci_omap_reset':
drivers/usb/host/ohci-omap.c:99:33: error: unused variable 'need_transceiver' [-Werror=unused-variable]
99 | int need_transceiver = (config->otg != 0);
Change the #ifdef check into an IS_ENABLED() check to make the
code more readable and let the compiler see where it is used.
