dechao_gong 30cbb23e6b arch/arm/rtl8721f: add I2C master driver support
Wire the shared Ameba I2C master lower-half (arch/arm/src/common/
ameba/ameba_i2c.c) into the RTL8721F (amebagreen2) build through a
per-chip header (ameba_i2c_chip.h), and register the RTL8721F EVB
buses at /dev/i2cN.

Per-chip differences from the other Ameba SoCs (non-secure register
bases, crossbar pinmux codes, APB clock masks and the fwlib
I2C_InitTypeDef layout) are isolated in ameba_i2c_chip.h; no change to
the shared driver is needed.

Verified end-to-end on hardware against a second Ameba board acting
as an I2C slave: address ACK, register write and read-back over
repeated-START, and bus scan all pass on I2C0 (PA22/PA23).
