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
