Jayshri Pawar 54c4c69f0b usb: cdns3: Add streams support to cadence USB3 DRD driver
This patch includes streams implementation changes.
The current changes has been validated on FPGA platform.

Enabled streams related interrupts only for streams capable endpoints.
Processed  PRIME and IOT interrupts related to streams capable endpoints.
Based on PRIME interrupt prime_flag is set and transfer is armed
otherwise just adding request to the deferred request queue.
For streams capable endpoints preparing TD with correct stream ID.

TDL calculation:
Updated tdl calculation based on controller versions.
1. For controller version DEV_VER_V2 :We have enabled USB_CONF2_EN_TDL_TRB
   bit in usb_conf2 register in DMULT configuration.
   This enables TDL calculation based on TRB, hence setting TDL in TRB.
2. For controller Version < DEV_VER_V2 : Writing TDL and STDL in ep_cmd
   register
3. For controller version > DEV_VER_V2 : Writing TDL in ep_tdl register.

Writing ERDY with correct Stream ID to ep_cmd register.
Added stream id related information to trace logs.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
