drm/i915: Select CONFIG_SHMEM
The driver requires shmfs as the backing filesystem to handle the buffer objects, so ensure it is selected if the user chooses to build our driver. Fixes: Bug 14662 - Dell E5500 kernel panic with KMS http://bugzilla.kernel.org/show_bug.cgi?id=14662 The revealing nature of the panic is the NULL function pointer dereference in read_cache_page_async().
