The i2c core driver will turn the platform device ID to busnum
When using platfrom device ID as -1, it means dynamically assigned
the busnum. When writing code, we need to make sure the busnum,
and call i2c_register_board_info(int busnum, ...) to register device
if using -1, we do not know the value of busnum

In order to solve this issue, set the platform device ID as a fix number
Here using 0 to match the busnum used in i2c_regsiter_board_info()

This driver has the following properties compared to the old driver:
1. Support for multiple interfaces.
2. Interrupt driven I/O as opposed to polling/busy waiting.
3. Support for _one_ repeated start (Sr) condition, which is enough
   for most real-world applications including all SMBus transfer types.
   (The hardware does not support issuing arbitrary Sr conditions on the
    bus.)

testing: SoC: at91sam9g45
	 - BQ20Z80 battery SMBus client.
	 - on a 2.6.38 kernel with several i2c clients (temp-sensor,
	   audio-codec, touchscreen-controller, w1-bridge, io-expanders)

instead of reading the registers everytime

the current implementation respect the following constrain:
 - allow 1 to n soc to be enabled
 - allow to have a virtual cpu type and subtype
 - always detect the cpu type and subtype and report it
 - detect if the soc support is enabled
 - prepare for sysfs export support
 - drop soc specific code via compiler when the soc not enabled
   (via cpu_is_xxx)

Today if we read the exid we will have the same value for 9g35 and 9m11
and we will need to check the cidr too

with the new implementation we just need to check the soc subtype

this will also allow to have specific virtual subtype for rm9200 which the
board will have to specify via at91rm9200_set_type(int) as we have no way to
detect it.

this implementation is inspired by the SH cpu detection support
