The type of phybase in the ssc_device struct should be changed from
resource_size_t to dma_addr_t.
Actually, the phybase in ssc_device structure is resource_size_t which
used to access the ssc device register.
Here, we use ssc register as dma source address or destination address,
so we convert it to dma_addr_t type. So, not need to change, am I right?
