When set, buffers will be mapped within 32-bit region
address space and in patching, if Shared or CmdBUffer is
not set for such buffers - patch the value with right shift
by 8. kmd does as below.
Map:
Shared or CmdBuffer : Mapped within 32bit.
HwAndCDMOrShared : Mapped within 32bit
others(HwAccess) : Mapped within 40bit
Patching:
Shared or CmdBuffer : as is
HwAndCDMOrShared : iova >> 8
others (HwAccess) : iova >> 8
Shared/CmdBuffer takes precedence over HwAndCDMOrShared.
