Exynos OHCI driver does not get registered if generic OHCI driver
is also selected as the macro PLATFORM_DRIVER gets re-defined to
'ohci_platform_driver' instead of 'exynos_ohci_driver'. Hence define
it separately.
Also, silences the following compilation warnings:
drivers/usb/host/ohci-hcd.c:1191:0: warning:
"PLATFORM_DRIVER" redefined [enabled by default]
drivers/usb/host/ohci-hcd.c:1110:0: note:
this is the location of the previous definition
drivers/usb/host/ohci-exynos.c:276:31: warning:
‘exynos_ohci_driver’ defined but not used [-Wunused-variable]
