For Intel platforms, pitch needs to be 64 byte aligned.
Kernel code vgem_gem_dumb_create which is platform generic code
doesnt do the alignment. This causes frame buffer creation to fail
on Intel platforms where the pitch is not 64 byte aligned.
tests: test run on Intel platforms with panel resolution 1366x768
