fsl-vivante-kernel-driver-handler.bbclass: Handle Vivante kernel driver provider
Enable the kernel to provide or not the Vivante kernel driver and dynamically set the proper providers per machine. The following options are supported: MACHINE_HAS_VIVANTE_KERNEL_DRIVER_SUPPORT Machine does or does not have support for the Vivante kernel driver, options are: 0 - machine does not have Vivante GPU driver support 1 - machine has Vivante GPU driver support MACHINE_USES_VIVANTE_KERNEL_DRIVER_MODULE Machine uses the Vivante kernel driver as module, options are: 0 - enable the builtin kernel driver module 1 - enable the external kernel module Signed-off-by: Otavio Salvador <otavio@ossystems.com.br>
