Expose the RTL8721F general-purpose UARTs through the shared Ameba serial driver in arch/arm/src/common/ameba. Only the chip-specific glue is added: a new ameba_uart_chip.h supplying the green2 register bases, IRQs, clock masks and UART TX/RX pin-mux function codes, plus the build wiring and a board port table registering UART0 at /dev/ttyS1. The common serial layer is reused unchanged. A new "uart" board config enables the driver with the serialrx and serialblaster examples and runtime TERMIOS support. Verified on RTL8721F EVB hardware with a PA24/PA25 loopback: single-message echo, 2600-byte serialrx/serialblaster throughput with no loss, and TERMIOS reconfiguration (CS7 data-bit truncation, parity and stop-bit ioctl round-trip, and 9600 baud reprogramming) all pass.
