mfd: lpc_sch: Partially revert "Add support for Intel Quark X1000"

Browse Source 
[ 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 ec689a8a81.
