tty: delete briq_panel.c driver
This driver is broken, as reported by Jiri, and to quote Ben: Just remove the driver, I don't think anybody cares. so I'm doing just that here.

- tristate 'Total Impact briQ front panel driver'
- depends on PPC_CHRP
- ---help---
- The briQ is a small footprint CHRP computer with a frontpanel VFD, a
- tristate led and two switches. It is the size of a CDROM drive.
-
- If you have such one and want anything showing on the VFD then you
- must answer Y here.

- To compile this driver as a module, choose M here: the
- module will be called briq_panel.
