This commits adds patches to hciattach for the following:
* Strict flow control setting
The hciattach application has a flow | noflow command line argument that is
currently only applied on the first configuration of the uart port. The
hciattach_rome plugin ignores this setting and assumes hardware flow
control is always supported. This commits makes hciattach obey the user flow
control indication.
* Modify hciattach_rome to set MAC address. The MAC address setting
feature in the rome plugin now works with the command line specified
MAC.
* Reduce verbosity. hciattach now accepts a "-v" verbose flag. By
default verbose output it omitted.
