config/arm: add Graviton2

Browse Source 
Add meson build configuration for Graviton2 platform
with 64-bit Arm Neoverse N1 cores. This patch makes the
following changes to generic Neoverse N1 config:

1. increase lcore limit to 64
2. increase memory support to 1TB
3. remove +crc from -march as that is default when setting armv8.2

For more information about Graviton2 platform, refer to:
