drm/amd/display: Remove redundant condition in VBA 314 func

Browse Source 
[WHY]
Coverity analysis this conditional code as DEADCODE.
The conditional statement is never true since
'MacroTileSizeBytes' is either 256 or 65536. Thus, the
code inside is the conditional statement is never reached.

[HOW]
Removed the conditional statement.
