i2c: add CSR SiRFprimaII on-chip I2C controllers driver

SiRFprimaII is the latest generation application processor from CSR’s
multi-function SoC product family.
The SoC support codes are in arch/arm/mach-prima2 from Linux mainline
3.0.
There are two I2C controllers on primaII, features include:
* Two I2C controller modules are on chip
* RISC I/O bus read write register
* Up to 16 bytes data buffer for issuing commands and writing data
at the same time
* Up to 16 commands, and receiving read data 16 bytes at a time
* Error INT report (ACK check)
* No-ACK bus protocols (SCCB bus protocols)

i2c-intel-mid: support for Moorestown and Medfield platform

(Updated to address Ben's comments. With regard to the message segment
restriction it's not something we hit on the actual platform so while
I will investigate that further I don't think its a blocker to submission.
At worst its a spot over-restrictive)

From: Wen Wang <wen.w.wang@intel.com>

Initial release of the driver. Updated and verified on hardware.

Cleaned up as follows

Alan Cox:
Squash down the switches into tables, and use the PCI ident field. We
could perhaps take this further and put the platform and port number into
this.
uint32t -> u32
bracketing of case statements
spacing and '!' usage
Check the speed (which is now 0/1/2) is valid and ignore otherwise.
Fix remaining problems/suggestions from Jean's review
Fix items from Ben's review

Arjan van de Ven:
Initial power management hooks

Yong Wang <youg.y.wang@intel.com>:
Shared IRQ support

Wen Wang <wen.w.wang@intel.com>:
D3 support
Fixes for OCT test runs
Interrupt optimisations

Hong Liu <hong.liu@intel.com>
The runtime PM code is working on the wrong device (i2c_adapter->dev).
The correct one should be pci_dev->dev. This breaks attached i2c
slave devices with runtime PM enabled. Slave device needs to runtime
resume parent device before runtime resuming itself, but we always get
error since we don't have pm_runtime callback for i2c_adapter->dev.
