[ Upstream commit 922e8ce883e59b52786b2c11656d84dc58ef084a ]
The IRQ support for SCH GPIO is not specific to the Intel Quark SoC. Moreover the IRQ routing is quite interesting there, so while it's needs a special support, the driver haven't it anyway yet.
Due to above remove basically redundant code of IRQ support.
This reverts commit ec689a8a8155ce8b966bd5d7737a3916f5e48be3.
