drm/vgem: Use PAGE_KERNEL in place of x86-specific PAGE_KERNEL_IO
Since PAGE_KERNEL_IO is specific to x86 and equivalent to PAGE_KERNEL
for our wrapping with pgprot_writecombine(), just use the common define.
drivers/gpu/drm/vgem/vgem_drv.c: In function 'vgem_prime_vmap':
>> drivers/gpu/drm/vgem/vgem_drv.c:238:53: error: 'PAGE_KERNEL_IO' undeclared (first use in this function)
addr = vmap(pages, n_pages, 0, pgprot_writecombine(PAGE_KERNEL_IO));
