i2c-parport: Add support for One For All remote JP1 interface 

This simple patch adds support to i2c-parport for the One For All remote
JP1 parallel port interfaces which can be found detailed at:

http://www.hifi-remote.com/jp1/hardware.shtml



These allow access to the internal configuration EEPROM on various
remote controls and there are a variety of Windows tools that make use
of this hardware. I have tested this patch with the "simple" parallel
port device and a One For All URC-7562 and confirmed that the data read
using the eeprom i2c driver matches that returned by the Windows "IR"
JP1 tool.

One For All JP1 parallel port adapter

-------------------------------------



The JP1 project revolves around a set of remote controls which expose

the I2C bus their internal configuration EEPROM lives on via a 6 pin

jumper in the battery compartment. More details can be found at:
