The Cadence Linux driver enables version 4 mode and 64-bit addressing in
Host Control 2 but retains the ADMA2 encoding in Host Control 1. QEMU
treats the transfer as 32-bit ADMA and uses 12-byte descriptors because
it only decodes Host Control 1.
Resolve the DMA type from both control registers and use 16-byte version
4 descriptors. Preserve the legacy 12-byte ADMA2 64-bit format when
version 4 mode is disabled.
