cnss2: Set proper SMMU attributes for collecting firmware RAM dump

Once SMMU stage 1 is enabled, set DOMAIN_ATTR_CB_STALL_DISABLE and
DOMAIN_ATTR_NO_CFRE SMMU attributes to disable context bank stall and
error fatal so that it is still able to collect firmware RAM dump over
PCIe bus even after SMMU fault happens.
