From: Nitin A Kamble <nitin.a.kamble at intel.com>

The fri2 kernel is hitting kernel BUGs while booting. See the YP
bug #3810 for more details.

FRI2 has 1GB of ram, hence the kernel sets 128MB for the vmalloc
allocation memory. And the emgd driver needs at least 256MB vmalloc
memory to work correctly. This commit specifies the vmalloc allocation
size to the kernel by the vmalloc=256MB boot parameter.

Adjusting the kernel's vmalloc allocation size fixes the kernel errors.

This fixes bug:
[Yocto #3810]
