[PATCH] misc: Kconfig: add a new dependency for HISI_HIKEY_USB

[Mauro Carvalho Chehab]

As warned by Randy:

	on x86_64:
	CONFIG_USB_ROLE_SWITCH=m
	and HISI_HIKEY_USB=y.

	ld: drivers/misc/hisi_hikey_usb.o: in function `hisi_hikey_usb_remove':
	hisi_hikey_usb.c:(.text+0x61): undefined reference to `usb_role_switch_unregister'
	ld: hisi_hikey_usb.c:(.text+0xa4): undefined reference to `usb_role_switch_put'
	ld: drivers/misc/hisi_hikey_usb.o: in function `hub_usb_role_switch_set':
	hisi_hikey_usb.c:(.text+0xd3): undefined reference to `usb_role_switch_get_drvdata'
	ld: drivers/misc/hisi_hikey_usb.o: in function `relay_set_role_switch':
	hisi_hikey_usb.c:(.text+0x54d): undefined reference to `usb_role_switch_set_role'
	ld: drivers/misc/hisi_hikey_usb.o: in function `hisi_hikey_usb_probe':
	hisi_hikey_usb.c:(.text+0x8a5): undefined reference to `usb_role_switch_get'
	ld: hisi_hikey_usb.c:(.text+0xa08): undefined reference to `usb_role_switch_register'
	ld: hisi_hikey_usb.c:(.text+0xa6e): undefined reference to `usb_role_switch_put'

Make it dependent on CONFIG_USB_ROLE_SWITCH.
