ARM|Driver: Add DPI Driver for emulation

Browse Source 
This driver provides support for Cadence JTAG BFM

The "jtag_dpi" driver implements a JTAG driver acting as a client for the
SystemVerilog Direct Programming Interface (DPI) for JTAG devices.
DPI allows OpenOCD to connect to the JTAG interface of a hardware model
written in SystemVerilog, for example, on an emulation model of
target hardware.

Tested on Ampere emulation with Altra and Altra Max models
