Michael Demeter 7714567c87 intel_mid_powerbtn: use MSIC read/write instead of ipc_scu
In the 2.6.36 kernel we did not have the MSIC driver. Changed
all ipc_scu_reads/writes to use the MSIC driver and defines.
Added a fix from the 2.6.36 kernel where the SCU FW could send
a power button interrupt to the IA32 FW and the kernel was not
running yet. This resulted in the interrupt not getting cleared
and the power button was ignored. this fix just clears the
interrupt on start-up.

Axel Lin 73d99a2244 platform-drivers-x86: convert drivers/platform/x86/* to use module_platform_driver()
This patch converts the drivers in drivers/platform/x86/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.
