Subject: [PATCH] config/arm: add Ampere Altra/AltraMax/AmpereOne platform
This patch add Ampere series platform support for DPDK:
1. Merging the eMAG and AmpereOne to the one struct implementer_ampere.
2. The microarchitecture of Altra/AltraMax is N1, which implementer/part_number
is defined in arm, so the definition of RTE_MAX_LCORE/RTE_MAX_NUMA_NODES
refers to the quadrant sub-numa definition in AltraMax 2P system.
3. Added basic definition of AmpereOne.
