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 Arm platform.

- It doesn't need to be split in 2 commits.
- Are you sure you want this change in 18.11? No risk?

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

Please fix your mail system. Because technically sending mail to a mailing list with this footer means everyone on the list should delete the mail.

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.

thunderx has only 96 cores. It the "thunderx2" which has more cores.
There no speerate config "thunderx2", it is using generic armv8 config.
So this specific line of change is not needed.

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.

Applied, thanks

Note: Arm64 replace by arm64 to comply with Honnappa's naming recommendation.
