Implement full support for OF SPI bindings. Now the driver can manage its own chip selects without any help from the board files and/or fsl_soc constructors. The "legacy" code is well isolated and could be removed as time goes by.

* The platform data structure is broken into two parts. The

* first is device specific information that help identify any

* unique features of a peripheral. The second is any
|
|
* information that may be defined by the board or how the device
|
|
* is connected externally of the chip.

*
|
|
* naming conventions:
|
|
* - platform data structures: <driver>_platform_data

* - platform data device flags: FSL_<driver>_DEV_<FLAG>
|
|
* - platform data board flags: FSL_<driver>_BRD_<FLAG>
