feat(ls1046afrwy): add ls1046afrwy board support

The LS1046A Freeway board (FRWY) is a high-performance computing,
evaluation, and development platform that supports the LS1046A
architecture processor capable of support more than 32,000 CoreMark
performance. The FRWY-LS1046A board supports the LS1046A processor,
onboard DDR4 memory, multiple Gigabit Ethernet, USB3.0 and M2_Type_E
interfaces for Wi-Fi, FRWY-LS1046A-AC includes the Wi-Fi card.
