No_Soft_Reset (NSR): This bit indicates that when the HECI host controller is
transitioning from D3hot to D0 due to power state command, it does not perform
an internal reset.

Power State (PS): This field is used both to determine the current power state
of the HECI host controller and to set a new power state. The values are:
00 = D0 state
11 = D3HOT state
The D1 and D2 states are not supported for this HECI host controller. When in
the D3HOT state, the HBA’s configuration space is available, but the register
memory spaces are not. Additionally, interrupts are blocked.
