Frank Chang 9a8c26c08c hw/dma: sifive_pdma: claim bit must be set before DMA transactions 
Real PDMA must have Control.claim bit to be set before
Control.run bit is set to start any DMA transactions.
Otherwise nothing will be transferred.

The following result is PDMA tested in U-Boot on Unmatched board:

=> mw.l 0x3000000 0x0                      <= Disclaim channel 0
                                              (Channel 0 is not claimed)
=> mw.l 0x3000004 0x55000000               <= wsize = rsize = 5 (2^5 = 32 bytes)
=> mw.q 0x3000008 0x2                      <= NextBytes = 2
=> mw.q 0x3000010 0x84000000               <= NextDestination = 0x84000000
=> mw.q 0x3000018 0x84001000               <= NextSource = 0x84001000
=> mw.l 0x84000000 0x87654321              <= Fill test data to dst
=> mw.l 0x84001000 0x12345678              <= Fill test data to src
=> md.l 0x84000000 1; md.l 0x84001000 1    <= Dump src/dst memory contents
