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.
