d3bf3d84d3 hisi_sas: add v2 channel interrupt handler
This also includes broadcast handler. Unlike v1 hw, broadcast does not
have its own dedicated interrupt.

94eac9e1ab hisi_sas: add v2 hw init
Add code to initialise the hardware.

Support is also added to deal with the "am-max-transmissions" (amt)
limitation in hip06 controller #1. This is how many connection requests
we can send on the system bus before waiting for a response.  Due to
chip bus design, controller #1 is limited to 32 amt, while, by design, a
controller supports 64.  The default value for the nibbles in the
relevant registers is 0x40; these need to be programmed with 0x20.
