Revert "WORKAROUND: mkbp: Remove KEY_BATTERY from valid keys."

This reverts commit 20dd2301234bc0f57018e4b51380e53f652ac30c.

This temporary workaround eliminated bug introduced by commit:
  688c20f CHROMIUM: Strengthen ghosting algorithm.

That CL introduced a bug where the virtual key, KEY_BATTERY, falsely
ghosted to a bunch of other key sequences.  That change is also being
reverted.
