[centec]: Add centec arm64 architecture support for E530 (#4641)
summary of E530 platfrom:
 - CPU: CTC5236, arm64
 - LAN switch chip set: CENTEC CTC7132 (TsingMa). TsingMa is a purpose built device to address the challenge in the recent network evolution such as Cloud computing. CTC7132 provides 440Gbps I/O bandwidth and 400Gcore bandwidth, the CTC7132 family combines a feature-rich switch core and an embedded ARM A53 CPU Core running at 800MHz/1.2GHz. CTC7132 supports a variety of port configurations, such as QSGMII and USXGMII-M, providing full-rate port capability from 100M to 100G.
- device E530-48T4X: 48 * 10/100/1000 Base-T Ports, 4 * 10GE SFP+ Ports.
- device E530-24X2C: 24 * 10 GE SFP+ Ports, 2 * 100GE QSFP28 Ports.

add new files in three directories:
device/centec/arm64-centec_e530_24x2c-r0
device/centec/arm64-centec_e530_48t4x_p-r0
platform/centec-arm64
