power: vexpress: fix -Wvoid-pointer-to-enum-cast warning
When building with clang 18 I see the following warning:
| drivers/power/reset/vexpress-poweroff.c:124:10: warning: cast to smaller integer type 'enum vexpress_reset_func' from 'const void *' [-Wvoid-pointer-to-enum-cast]
| 124 | switch ((enum vexpress_reset_func)match->data) {
This is due to the fact that `match->data` is a void* while `enum vexpress_reset_func`
has the size of an int. This leads to truncation and possible data loss.
