Version 4 SDMA selects its system address from the registers also named

resume a transfer that stopped at the configured SDMA buffer boundary.
Resume 32-bit addressing after an access completes the lower 32 bits of
the ADMA System Address register. For 64-bit addressing, wait until an
access completes the upper 32 bits so software can update the low half
before the high half without starting from a mixed address.
