[IDF] arm-pod7: Configure hugepages and cpupinning variables for armpod7

For non-dpdk scenarios we define as cpu config:
        0,1 for OS
        2-7 for nova
For dpdk scenarios we define as cpu config:
        0,1 for OS,
        2,3 for DPDK drivers and processes
        4-7 for nova

Dpdk config is also provided for the 3 thunderx nodes which currently
serve as KVM nodes. The config is similar to the config above with
cores 4-47 being used for nova.
