Alex Elder 1bb3c724e8 greybus: create host device cport id map
A Greybus host device has a pool of CPort Ids it can use.  When we
establish a connection with a CPort on another module we will need
to allocate one from those that are available.

This patch adds a bitmap to the greybus host device structure that
allows cport ids to be allocated and freed as needed.
