[Yang Zhong <yang.zhong@intel.com>]

This patch can enable numa support for 'info sgx' command
in the monitor, which can show detailed SGX EPC sections
info.

(qemu) info sgx
 SGX support: enabled
 SGX1 support: enabled
 SGX2 support: enabled
 FLC support: enabled
 SECTION #0: size=67108864
 SECTION #1: size=29360128

 The QMP interface show:
 (QEMU) query-sgx
 {"return": {"sgx": true, "sgx2": true, "sgx1": true, "sections": \
 [{"index": 0, "size": 67108864}, {"index": 1, "size": 29360128}], "flc": true}}
