mtd: maps: fix -Wvoid-pointer-to-enum-cast warning
When building with clang 18 I see the following warning:
| drivers/mtd/maps/physmap-versatile.c:209:25: warning: cast to smaller
| integer type 'enum versatile_flashprot' from 'const void *' [-Wvoid-pointer-to-enum-cast]
| 209 | versatile_flashprot = (enum versatile_flashprot)devid->data;
This is due to the fact that `devid->data` is a void* while `enum versatile_flashprot`
has the size of an int.
Cast `devid->data` to a uintptr_t to silence the above warning for clang
builds using W=1.
