LF-4274 i3c: master: svc: enable the interrupt in the enable ibi function
If enable interrupt in the svc_i3c_master_bus_init() but do not call
enable ibi in the device driver, it will cause a kernel dump in the
svc_i3c_master_handle_ibi() when a slave start occurs on the i3c bus,
because the data->ibi_pool is not initialized.
So only enable the interrupt in svc_i3c_master_enable_ibi() function.
