config/thunderx: disable C11 memory model ring

On thunderx and octeontx, ring_perf_autotest and
ring_pmd_perf_autotest test shows better performance
when disabling CONFIG_RTE_RING_USE_C11_MEM_MODEL.
On the other hand, Enabling CONFIG_RTE_RING_USE_C11_MEM_MODEL
shows better performance on thunderx2.
Since thunderx2 is using the default armv8 config,
no particular change is required.
