cxgb4: Add HMA support
HMA(Host Memory Access) maps a part of host memory for T6-SO memfree cards.
This commit does the following:
- Query FW to check if we have HMA support. If yes, the params will
return HMA size configured in FW. We will dma map memory based
on this size.
- Also contains changes to get HMA memory information via debugfs.
