By default, pCPU is allowed to request software SRAM buffer
from given region in TCC buffer driver only if this pCPU is
set in the target region's CPU affinity configuration.
This check shall be disabled for software SRAM virtualization
usage in ACRN service VM, because software SRAM buffers are
requested by ACRN DM on behalf of user VM, but ACRN DM and
user VM may run on different CPUs while the target software
SRAM region may be configured only for pCPUs that user VM runs on.
This patch turns off such affinity check in TCC driver when
initializing vSSRAM for user VM.
