Rong Chang a81f0cd547 Add I2C transmit/receive function ...

Implement a generalized I2C transmit-receive function that
write-then-read blocks of raw data. Original 8-bit and 16-bit
read/write functions are refactored.

SMBus read-block protocol for ASCII string is also implemented
based on this API.

BUG=chrome-os-partner:8026,8316
TEST=manual:
  Type 'lightsaber' to check 8-bit read/write.
  Type 'charger' to check 16-bit read.
  Type 'charger input 4032' to check 16-bit write.
