Mulin Chao aa2db44011 nuc: Add state machines to handle i2c master stall bus and call i2c_xfer again. ...

Create two state machines SMB_WRITE_SUSPEND and SMB_READ_SUSPEND to handle i2c
master stall bus and call i2c_xfer again. Notice we should disable i2c
interrupt since cannot read/write SDA reg to clear interrupt pending bit.

Modified drivers:
1. i2c.c: Modified to handle calling i2c_xfer twice or more.

BUG=chrome-os-partner:34346
TEST=make buildall -j; test nuvoton IC specific drivers
BRANCH=none
