mailbox: mpfs-mbox: fix Driver Model private data handling

The MPFS mailbox driver declares priv_auto but also allocates a second
private data structure in the legacy probe path and overwrites the
device’s private pointer using dev_set_priv().

This results in leaking the auto-allocated private data and replacing
the driver’s private state mid-probe, which is incorrect usage of the
U-Boot Driver Model and can lead to undefined behavior.

Remove the redundant allocation and dev_set_priv() call so that the
driver consistently uses the auto-allocated private data provided by
U-Boot.
