Subject: drm/mgag200: fix build on alpha arch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When building imgag200 for the alpha architecture it fails like this:
mgag200_drv.c:233:9: error: implicit declaration of function ‘vmalloc’
  233 |  bios = vmalloc(size);
      |         ^~~~~~~
      |         kmalloc

When building for other architectures vmalloc.h is pulled in via some
other header file - for example asm-generic/io.h.
Use an explicit include of vmalloc.h to fix the build.
