Hi,
Intel Quark X1000 consists of two SPI controllers which can be PCI enumerated.
SPI-PXA2XX PCI layer doesn't support it. Thus, we add support for Intel Quark
X1000 SPI as well.

* Improve the interrupt handler.
* Move 'irq_set_handler_data' together with 'irq_set_chained_hanlder'.
* Remove unncessary comments.
[PATCH 2/3]
* Change all 'readl'&'writel' to 'dwapb_read'&'dwapb_write'.
This patch enables suspend and resume mode for the power management, and
it is based on Josef Ahmad's previous work.
