Subject: [PATCH] drm: vmwgfx: include linux/highmem.h

In order to call kmap_atomic() etc, we need to include linux/highmem.h:

drivers/gpu/drm/vmwgfx/vmwgfx_blit.c: In function 'vmw_bo_cpu_blit_line':
drivers/gpu/drm/vmwgfx/vmwgfx_blit.c:377:4: error: implicit declaration of function 'kunmap_atomic'; did you mean 'in_atomic'? [-Werror=implicit-function-declaration]
  377 |    kunmap_atomic(d->src_addr);
      |    ^~~~~~~~~~~~~
      |    in_atomic
drivers/gpu/drm/vmwgfx/vmwgfx_blit.c:391:5: error: implicit declaration of function 'kmap_atomic_prot' [-Werror=implicit-function-declaration]
  391 |     kmap_atomic_prot(d->dst_pages[dst_page],
      |     ^~~~~~~~~~~~~~~~
drivers/gpu/drm/vmwgfx/vmwgfx_blit.c:390:16: warning: assignment to 'u8 *' {aka 'unsigned char *'} from 'int' makes pointer from integer without a cast [-Wint-conversion]
  390 |    d->dst_addr =
      |                ^
drivers/gpu/drm/vmwgfx/vmwgfx_blit.c:403:16: warning: assignment to 'u8 *' {aka 'unsigned char *'} from 'int' makes pointer from integer without a cast [-Wint-conversion]
  403 |    d->src_addr =
      |                ^
