FS#13195: rocker: Improved root menu keymap (Howard Richardson)

This patch addresses a keymapping anomaly on the Rocker. Currently the
Power button when pressed inside a sub-menu will return you to the root
of the menu. However when pressed again it returns you to the sub-menu
you were in previously. This is at odds with how other ports work and
makes it difficult to return to the WPS without manually selecting it on
the root menu.

This patch copies the behaviour of the home button on the Sansa Clip+.
Pressing it once will exit a sub-menu and bring you back to the root
menu. Pressing it again takes you to the WPS. No functionality is lost
or covered up by making this reassignment.
