Hi Thomas
I am taking the opportunity to update RTE_MAX_LCORE for future releases 
of dpdk.  As we are switching to meson builds soon so this is an 
appropriate opportunity to update the value and keep in step with the 
hardware. Older stable release can continue to use the smaller value 
found in deconfig..
