drm/amd/display: Add PSP FW version mask.
[Why]
PSP version format is AB.CD.EF.GH, where CD and GH is the main version.
current psp version check for dmcub loading dmcu check 0x00110029, in
case of some psp version eg: 0x00110227 which main version should be
0x00110027, will result in unexpeceted dmcub loading dmcu FW.
[How]
Add psp version mask 0x00FF00FF for checking version.
