locking for 2nd port and hwraid was added from vendor's GPL code which
doesn't comply with current kernel coding style.
- moved all global variables into host_priv
- renamed locks
- sanetized acquire() and release() parameter list

similar to mv_sata, use nr-ports attribute from device tree.
import and adapt locking code from vendor GPL sources.
add dma controller handling, it may be used in future to avoid
full core resets similar to the vendor SDK's "progressive cleanup"
function.
this is still very dirty and aimed to first of all do things
quite exactly like the reference code. and it somehow works.
obviously there is lots of room for improvement :)
