habanalabs/gaudi: use HBM_ECC_EN bit for ECC ERR
driver should use ECC info from FW only if HBM ECC CAP is set. otherwise, try to fetch the data from MC regs only if security is disabled. Signed-off-by: Ohad Sharabi <osharabi@habana.ai> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Signed-off-by: Oded Gabbay <ogabbay@kernel.org>
