Prike Liang c56525193b drm/amdgpu/mes11: disable MES RS64 process/gang context loading
The MES RS64 local memory process/gang context index may be updated,
saved, or restored improperly during queue eviction and restore cycles.
Enabling RS64 memory for MES process/gang context loading introduces
two known issues:
  1. Performance regression on userq due to improper context index
     handling during RS64 memory access.
  2. KFDIPCTest.BasicTest failure on Navi31/32/33: the IPC buffer
     GPU VA mapping is not correctly reflected in the restored RS64
     process context, causing GPU page faults on the IPC shared
     buffer address, which eventually leads to MES firmware becoming
     unresponsive and requiring a full GPU reset to recover.
Temporarily disable MES RS64 process/gang context loading until both
issues are resolved.
