nv-virtio-poc: Add missing header

Browse Source 
In Linux v6.10 the nv-virtio-poc driver fails to build and the following
error is seen ...

 drivers/nv-virtio/nv-virtio-console-poc.c:277:13:
  error: implicit declaration of function 'remap_pfn_range';
  did you mean 'vmap_page_range'? [-Werror=implicit-function-declaration]
  277 |         if (remap_pfn_range(vma, vma->vm_start, ipa_pfn,
      |             ^~~~~~~~~~~~~~~
      |             vmap_page_range

Upstream commit 22bcc915ae91 ("kfifo: don't use "proxy" headers")
updated some kernel headers to only 'include what is used' and exposed
that the nv-virtio-poc driver is not explicitly including 'linux/mm.h'.
The function remap_pfn_range() has been defined in 'linux/mm.h' since
Linux v2.6 and so fix this by always including 'linux/mm.h'.
