[PATCH] staging: kpc2000: Fix build error without CONFIG_UIO

[YueHaibing]

Fix gcc build error while CONFIG_UIO is not set

ERROR: "uio_unregister_device" [drivers/staging/kpc2000/kpc2000/kpc2000.ko] undefined!
ERROR: "__uio_register_device" [drivers/staging/kpc2000/kpc2000/kpc2000.ko] undefined!

Add UIO Kconfig dependency to fix this.
