Subject: [PATCH v2 1/1] solos-pci: Fix regression introduced by newest firmware

The newest FPGA firmware on the Solos processors correctly signals carrier transitions, bitrate, etc.

The driver previously ignored these messages, and the physical state was always ATM_PHY_SIG_UNKNOWN.

Now that the board reports its state, we expose a bug whereby the transition from UNKNOWN to LOST causes us to release all VC's.

We don't delete any VC's, but instead just send an indication of carrier change.
