accel/amdxdna: Update message DMA buffer allocation
The latest firmware requires the message DMA buffer to
- have a minimum size of 8K
- use a power-of-two size
- be aligned to the buffer size
- not cross 64M boundary
Update the buffer allocation logic to meet these requirements and support
the latest firmware.
