Enable Vivante kernel driver dynamic provider

The linux-imx.inc based kernels now can dynamically provide the
Vivante kernel driver and satisfy the runtime dependency added for the
Vivante GPU user space libraries. The beauty of this solution is that
it makes ease for 3rd party kernel to reuse the same infrastructure
and use the external module easily.
