This patch adds a helper function to the MCE driver to allow its
clients to issue UPDATE_CSTATE_INFO requests, without having to
setup the CPU context struct.

We introduced a struct to encapsulate the request parameters, that
clients can pass on to the MCE driver. The MCE driver gets the
parameters from the struct and programs the hardware accordingly.
