dechao_gong af49db4483 arch/arm/rtl8720f: add I2C master driver support
Wire the RTL8720F to the shared Ameba I2C master driver
(arch/arm/src/common/ameba/ameba_i2c.c), reusing it unchanged.

Add the per-chip header arch/arm/src/rtl8720f/ameba_i2c_chip.h supplying
the chip's I2C wiring: two controllers (I2C0/I2C1) on their non-secure
register aliases (0x401c8000 / 0x401c9000), the APBPeriph function/clock
masks, the crossbar SCL/SDA pad-mux codes (59/60 and 61/62), and
AMEBA_I2C_HAS_DMA_FIELDS=1 (the chip's I2C_InitTypeDef carries the DMA
request-level fields).

Add the board glue: rtl8720f_i2c.c registers I2C0 at /dev/i2c0
(PA22/PA23) and I2C1 at /dev/i2c1 (PA24/PA25), plus the build wiring
(Make.defs / CMakeLists.txt / ameba_board.mk pull in the common driver
and the fwlib ram_common/ameba_i2c.c data-table source), the bringup
registration hook and the board header declaration.

Add the i2c defconfig (minimal NSH with the i2ctool) and document the
config in the board index.
