drivers: ipm: ipm_mbox: fix qualifier warning in callback

Browse Source 
mbox_msg::data is a const pointer, but ipm_callback_t expects a
volatile void * payload. Passing the mailbox payload through the
IPM callback was triggering compiler warnings about discarded
qualifiers.

Convert the mailbox payload pointer to the IPM callback payload
type via a uintptr_t round-trip to avoid -Wdiscarded-qualifiers
or -Wcast-qual noise without changing the runtime behavior.

fix:https://github.com/zephyrproject-rtos/zephyr/issues/102057
