After __cpuidle_register_device, the cpu incs are added up, but decs
are not, thus the module refcount is not match. So the module "exit"
function can not be executed when we do remove operation. Move
module_put into __cpuidle_register_device to fix it.

Add cpuidle support for e500 family, using cpuidle framework to
manage various low power modes. The new implementation will remain
compatible with original idle method.
Initially, this supports PW10, and subsequent patches will support
PW20/DOZE/NAP.

For B4 platform, MPIC EISR register is in reversed bitmap order,
instead of "Error interrupt source 0-31. Bit 0 represents SRC0."
the correct ordering is "Error interrupt source 0-31. Bit 0

Normally when we haven't implemented an alignment handler for

The alignment handler uses the DSISR (or a pseudo one) to locate
the right handler. Unfortunately ldbrx and stdbrx overlap lfs and
