[PATCH v2 05/17] Platform: OLPC: Move OLPC config symbol out of x86 tree

[Lubomir Rintel]

There are ARM OLPC machines that use mostly the same drivers, including
EC infrastructure, DCON and Battery.

While at that, fix Kconfig to allow building this as a module.

Changes since v1:
- Use 'depends on OLPC && X86' idiom (thanks Andy Shevchenko)
