drivers: misc: devmux: fix init signature

gmarull · henrikbrixandersen · commit 1494cdb0bf3a · 2025-03-10T21:32:40.000+01:00
It is no longer possible to use other signatures other than
`int fn(const struct device *)`. Just cast the device pointer,
safe in this context because CONFIG_DEVICE_MUTABLE=y.
