Add a board port for the Raspberry Pi Pico 2 W (RP2350 + Infineon CYW43439). The board reuses the existing raspberrypi-pico-2 port and adds support for the onboard CYW43439 Wi-Fi device, driven through a new RP2350 PIO-based gSPI transport (arch/arm/src/rp23xx/rp23xx_cyw43439.c) that plugs into NuttX's existing bcm43xxx (bcmf) FullMAC driver. A telnet defconfig is provided that associates to an AP (NETINIT WAPI), obtains a DHCP lease, and exposes an NSH shell over TCP/telnet. This board port and the RP2350 PIO-gSPI CYW43439 driver were developed with Claude Code (Anthropic's agentic coding tool) and validated on real Pico 2 W hardware: Wi-Fi association, DHCP, and a TCP/telnet session over the CYW43439.
