n900: modem driver plugin for Nokia N900

This patch adds a modem driver plugin for the Nokia N900 internal
modem. It controls the modem using the appropriate GPIO lines and thus
works without the Maemo userspace.

This plugin can run natively on the N900 with either Maemo or Meego
kernels. However, it conflicts with the Maemo userspace, for which
isigen should be used instead.
