feat(plat/nxp/ls1028ardb): add ls1028ardb board support
The LS1028A reference design board (RDB) is a computing,
evaluation, and development platform that supports industrial
IoT applications, human machine interface solutions, and
industrial networking.
It supports the following features:
1. Layerscape LS1028A dual-core processor based on Cortex-A72
at 1.3 GHz.
2. 4 GB DDR4 SDRAM w/ECC
3. Support Ethernet:
1) x1 RJ45 connector for 1Gbps Ethernet support w/TSN, 1588
2) x4 RJ45 connector for 1Gbps Ethernet switch support w/TSN,
1588 (QSGMII)
3. With Basic Peripherals and Interconnect
2x M.2 Type E slots with PCIe Gen 3.0 x1
1x M.2 Type B slot with SATA 3.0 (resistor mux with 1 Type E slot)
1x Type A USB 3.0 super-speed port
1x Type C USB 3.0 super-speed port
1x DisplayPort interface
2x DB9 RS232 serial ports
2x DB9 CAN interfaces
1x 3.5 mm audio out
2x MikroBUS™ sockets
