accel/amdxdna: Clear mailbox interrupt register during channel creation 



The mailbox interrupt register is not always cleared when a mailbox channel
is created. This can leave stale interrupt states from previous operations.

Fix this by explicitly clearing the interrupt register in the mailbox
channel creation function.
