kernel: gpio-button-hotplug: update to use threaded irq's
Many gpio controllers 'cansleep' due to the fact that they are behind busses e.g. i2c etc. Using threaded irq's allows for 'sleep-able' gpio's to be used. Signed-off-by: Pushpal Sidhu <psidhu@gateworks.com> Signed-off-by: Tim Harvey <tharvey@gateworks.com> SVN-Revision: 48696
