Browse Source 
Starting from Ampere+ chips, PMASYS control register layout has
been re-organized to support multiple PMA streaming channels.
In accordance with this update perf HALs to replace legacy register with
new registers.

The mapping between the legacy register and new register fields can
be found here: http://nvbugs/2332044/16.
