hw: allwinner-i2c: Fix TWI_CNTR_INT_FLAG on SUN6i SoCs

TWI_CNTR_INT_FLAG is W1C(write 1 to clear and write 0 has non-effect)
register on SUN6i based SoCs, we should lower interrupt when the guest
set this bit.

The linux kernel will hang in irq handler(mv64xxx_i2c_intr) if no
device connected on the i2c bus, next is the trace log:

{hw/i2c,docs/system/arm}: Allwinner TWI/I2C Emulation

This patch implements Allwinner TWI/I2C controller emulation. Only
master-mode functionality is implemented.

The SPL boot for Cubieboard expects AXP209 PMIC on TWI0/I2C0 bus, so this is
first part enabling the TWI/I2C bus operation.

Since both Allwinner A10 and H3 use the same module, it is added for
both boards.

Docs are also updated for Cubieboard and Orangepi-PC board to indicate
I2C availability.
