drm/amd/display: Fix DC definition of PMFW Pstate table for DCN316

Browse Source 
[Why]

During DC init, we read power management tables from PMFW. This info is
exchanged in the form of a binary blob inside gpu memory. In order to
parse the binary blob, the correct struct needs to be used.

[How]

Fix dcn316's definition of the DfPstateTable_t struct to align with PMFW
