This pull request to update two third party vendor drivers to be included
in A-rev delivary image for Dell IoT project. These drivers are:

1. Exar USB UART driver - fixes to Rx fail after resume from S3/S4
2. Redpine ver. 1.2.RC4 - multiple fixes and enables lot's of new features.

While the Exar driver is fileterd out of builds on s390 systems, Redpine
driver will compile only on amd64 systems. Also, the Redpine driver will
bind only to the RS9113 Wifi-BT combo chips probed on SDIO or USB buses.
Support for other Redpine chipsets will be supported by the driver carried
by the 4.4.X kernel from mainline.

Tested on Dell IoT gateway DVT-2 boards.
