[v2] config: enable more than 128 cores for Arm64 platform

  When running dpdk applications on cores whose ids are bigger
than original max_core setting, eal error as below:
EAL: Detected 104 lcore(s)
EAL: Detected 2 NUMA nodes
EAL: invalid core list
-l CORELIST core indexes between 0 and 128

The fix is to increase max_core to 256 on Arm64 platform.

This change makes thunderx config to 256 cores not armv8. 
For generic config, it needs to be under "flags_generic"
not under "flags_cavium". Just like you did for updating
defconfig_arm64-armv8a-linuxapp-gcc config instead of
defconfig_arm64-thunderx-linuxapp-gcc

Config to 256 cores for both flags_generic and flags_cavium in V3.
For thunderx, it will do meson build according to flasg_cavium instead of flags_generic.
And there is no inheritance relationship between the two flags.
