New port: AIGO EROS Q / EROS K

The Q and K have a slightly different case, but the hardware under the
shell is completely identical.

These models are rebadged versions:

 * Hifiwalker H2   (== Q)
 * AGPTek H3       (== K)
 * Surfans F20     (== K)

Other notes:

  * Significant improvements in the shared Hiby-platform launcher/loader
    * SD card can theoretically be hot-swapped now
    * Support external USB mass storage!
  * Some consolidation of Hiby-platform targets
  * Some consolidation of plugin keymaps

Todo/known issues:

 * Keymaps need to be gone over properly
 * Convert to HAVE_SCROLLWHEEL?
