Jamin Lin a66c02ea9d hw/i2c/aspeed: Fix wrong I2CC_DMA_LEN when I2CM_DMA_TX/RX_ADDR set first 
In the previous design, the I2C model would update I2CC_DMA_LEN (0x54) based on
the value of I2CM_DMA_LEN (0x1C) when the firmware set either I2CM_DMA_TX_ADDR
(0x30) or I2CM_DMA_RX_ADDR (0x34). However, this only worked correctly if the
firmware set I2CM_DMA_LEN before setting I2CM_DMA_TX_ADDR or I2CM_DMA_RX_ADDR.

If the firmware instead set I2CM_DMA_TX_ADDR or I2CM_DMA_RX_ADDR before setting
I2CM_DMA_LEN, the value written to I2CC_DMA_LEN would be incorrect.

To fix this issue, the model should be updated to set I2CC_DMA_LEN when the
firmware writes to the I2CM_DMA_LEN register, rather than when it writes to the
I2CM_DMA_RX_ADDR and I2CM_DMA_TX_ADDR registers.
