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

Browse source 
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.
