Switch over to using olpc-ec.h in multiple steps, so as not to break builds.
This covers every driver that calls olpc_ec_cmd().

When the system is woken due to a RTC event, report the wakeup
event on the relevant rtc device (if it can be found).

Produce wakeup events for the XO-1's power button, lid switch
and ebook switch, taking care to only produce events when the
states have changed.

EC events indicate change in AC power connectivity, battery state of
charge, battery error, battery presence, etc. Send notifications to
the power supply subsystem when changes are detected.

Configure the XO-1's lid switch GPIO to trigger an SCI interrupt,
and correctly expose this input device which can be used as a wakeup
source.

The EC in the OLPC XO-1 delivers GPE events to provide various
notifications. Add the basic code for GPE/EC event processing and
enable the ebook switch, which can be used as a wakeup source.

The System Control Interrupt is used in the OLPC XO-1 to control various
features of the laptop. Add the driver base and the power button
functionality.
This driver can't be built as a module, because functionality added in
future patches means that some drivers need to know at boot-time whether
SCI-based functionality is available.
