First NXP platform support for wolfIP. Adds a bare-metal port for the LPCXpresso54S018M development board (Cortex-M4F, 96 MHz) with DHCP, ICMP ping, and TCP echo server over 100 Mbps Ethernet (LAN8720A PHY). The Ethernet driver is split into a shared lpc_enet/ component (Synopsys DesignWare Ethernet QoS with enhanced descriptors) and board-specific code in lpc54s018/, matching the existing stm32/stm32h563 structure for easy reuse across other NXP LPC boards. Tested: DHCP lease acquisition, ICMP ping (<1 ms), TCP echo on port 7.
