Add cmdq_pkt_poll_addr function to support CMDQ user making an instruction for polling a specific address of hardware rigster to check the value with or without mask. POLL is a legacy operation in GCE, so it does not support SPR and CMDQ_CODE_LOGIC. To support polling the register address which doesn't have the subsys id, CMDQ users need to make an instruction with GPR and CMDQ_CODE_MASK operation to move the register address to be poll into GPR. Then users can make an POLL instruction with GPR to poll the register address assigned in previous instruction.

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 reStructuredText 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.
