From: Dong Aisheng <dong.aisheng@linaro.org>

The General Purpose Registers (GPR) is used to select operating modes for
general features in the SoC, usually not related to the IOMUX itself,
but it does belong to IOMUX controller.
We simply provide an convient API for driver to call to write/read the general
purpose register bits if needed.

Signed-off-by: Dong Aisheng <dong.aisheng@linaro.org>
---
ChangeLog v2->v3:
* add spinlock to protect write
* add a parameter for read API to distinguish with return error
ChangeLog v1->v2:
* add gpr read api
* change api name a bit to *_write and *_read
* add -EPROBE_DEFER support
* define macros for gpr registers for imx6q
* change driver loadding priority to postcore_init at satisfy clients driver
  to use imx_pinctrl_gpr_{read | write} APIs at best

spin_lock_irqsave? We don't know whether people call it in isr.

Yes, we definitely should support call it in isr.
thanks for pointing out this.
Will fix it in next version.
