gpio: Add PMIC GPIO block support
Moorestown has PMIC chip which contains GPIO blocks. The PMIC chip is connected to Langwell by SPI interface. So this GPIO driver will be regarded as SPI GPIO expander though the actual GPIO access is through IPC and SRAM. The SPI master contoller will probe this device driver by parsing SPIB table. Cleaned up for new IPC, GPE removed and some printk and other tidying by Alan Cox. Fixes for points noted by Matthew Garrett Signed-off-by:Alek Du <alek.du@intel.com> Signed-off-by:
