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

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)
