With kernel 4.14 the OpenWrt specific module name collides with the
upstream added module for Mediatek ARM Socs.
During addition of preliminary support for kernel 4.14, the config
symbol used by the out of tree driver was already renamed but the ramips
kernel package wasn't updated.
Fix the build error by updating the config and kernel module name for
the kernel package.
