dechao_gong 18d2ae253c arch/arm/rtl8720f: add UART master driver support
Wire the shared common UART driver
(arch/arm/src/common/ameba/ameba_uart.c) into RTL8720F.  Add an
ameba_uart_chip.h supplying the per-chip UART parameters: two
general-purpose controllers (UART0/UART1), their non-secure register
bases (0x401C3000 / 0x401C4000 -- the fwlib UART_DEV_TABLE points at
the non-secure alias), NVIC vectors, APBPeriph function/clock masks
and the crossbar TX/RX pad-mux function codes.

The fwlib ROM UART routines index data tables (UART_DEV_TABLE,
APBPeriph_UARTx) that live in fwlib ram_common/ameba_uart.c, so that
source is compiled in when CONFIG_AMEBA_UART is set.  Wire
CONFIG_AMEBA_UART into Make.defs/CMakeLists/ameba_board.mk, add the
board port table (UART0 at /dev/ttyS1, PA22 TX / PA23 RX, 115200 8N1)
with bringup registration, a uart config and board documentation.

Hardware-verified on rtl8720f_evb: serialrx/serialblaster over a
PA22-to-PA23 TX/RX loopback transferred all 2600 bytes intact.
