mtd: rawnand: fix -Wvoid-pointer-to-enum-cast warning
When building with clang 18 I see the following warning:
| drivers/mtd/nand/raw/vf610_nfc.c:853:17: warning: cast to smaller integer
| type 'enum vf610_nfc_variant' from 'const void *' [-Wvoid-pointer-to-enum-cast]
| 853 | nfc->variant = (enum vf610_nfc_variant)of_id->data;
This is due to the fact that `of_id->data` is a void* while `enum vf610_nfc_variant`
has the size of an int.
Cast `of_id->data` to a uintptr_t to silence the above warning for clang
builds using W=1.
