patches: add ubuntu 12.04 lts kernel ibi support

Add a series of patches that should be applied tot the ubuntu
12.04-LTS kernel (linux 3.5.0) in order for working with the wilink8
r8.a6.02 sdio in-band interrupt support.
This series of patches add new APIs to the sdio_irq driver that are
used by the r8.a6.02 modified drivers.
Without this patch set the driver would not build with the 12.04-LTS
kernel.

Note: The build script is not applying this patch set. It needs to
be manually applied to the linux pc kernel source followed buy a
build/install of the modified kernel to the Ubuntu PC.
