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.
