lib: utils/serial: Add support for Altera JTAG UART

Browse Source 
Altera provides a JTAG UART core that provides virtual UART over JTAG
and can coexist with their virtual JTAG. [1] This core has already been
supported by Linux and the programming interface has always been stable.

Add support for it to OpenSBI to ease JTAG prototype bringing up.

The driver follows the device tree binding in mainline Linux. [2]
