hw/i2c/aspeed: Fix TXBUF transmission start position error
According to the ast2600 datasheet and the linux aspeed i2c driver,
the TXBUF transmission start position should be TXBUF[0] instead
of TXBUF[1],so the arg pool_start is useless,and the address is not
included in TXBUF.So even if Tx Count equals zero,there is at least
1 byte data needs to be transmitted,and M_TX_CMD should not be cleared
at this condition.The driver url is:
