Add a shared Ameba high-speed UART driver on top of the GPIO driver's common/ameba/ infrastructure, exposing UART0/UART1 through the NuttX serial upper half. - arch/arm/src/common/ameba/ameba_uart.c/.h: serial lower-half driver built on the SDK fwlib UART register layer (ROM symbol table). RX/TX dispatch through NuttX-native interrupts; TERMIOS get/set supported. The pins are muxed to the direction-specific UART crossbar function codes (TXD/RXD per controller) required by the amebadplus pinmux, and RX is pulled high through the SDK ROM. - arch/arm/src/common/ameba/Kconfig: AMEBA_UART option (selects SERIAL and ARCH_HAVE_SERIAL_TERMIOS) plus RX/TX buffer-size knobs. - arch/arm/src/rtl8721dx: wire ameba_uart.c into the Make/CMake builds and pull the fwlib ram_common UART table into the fwlib link set. - boards/arm/rtl8721dx/pke8721daf: board UART port table registering UART0 at /dev/ttyS1 (PB18/PB19, 115200), bring-up hook, and a uart NSH config with the serialrx/serialblaster examples. - Documentation: describe the driver and the uart board config. Verified on hardware (PKE8721DAF): pinmux routing, TX/RX and interrupt paths, and the TERMIOS ioctl path via loopback.
