[PATCH 0/2 v3] SPI: spi-pxa2xx: Add support for Intel Quark X1000 SPI controller

[Weike Chen <alvin.chen@intel.com>]

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.

v3:
[PATCH 1/2]
* Improve the commit message.
* A couple of minor fixes.
[PATCH 2/2]
* Set '.num_chipselect' to '1' instead of '4'.
* A couple of minor fixes.

v2:
  Split into two patches: one is for helper functions,
  and another is for quark supporting.

[PATCH 1/2]
* Add helper functions to access registers.
* Use 'switch' instead of 'if-else'.
[PATCH 2/2]
* Use 'switch' instead of 'if-else'.
* Add comments for the 'dds'&'clk_div' caculation.
* A couple of minor fixes.
