Subject: [PATCH v4 1/7] serial: exar: remove old Connect Tech setup

From: Parker Newman <pnewman@...necttech.com>

Preparatory patch removing existing Connect Tech setup code and
CONNECT_DEVICE macro.

Subsequent patches in this series will add in new UART family specific
setup code and new device definition macros to allow for supporting CTI
serial cards with Exar PCI IDs and CTI PCI IDs.

Signed-off-by: Parker Newman <pnewman@...necttech.com>
