We are using PTE_GRP1 for DMA operations to load firmware binaries but we are enabling PTE_GRP and flushing ATU cache much before in probe callbacks. This can cause issue if we try to load firmware runtime during system resume as probe callback will not be invoked hence PTE_GRP will not be enabled. Moreover it makes more sense to flush the cache after register configuration. Move PTE group register configuration to acp-loader within pre_fw_run callback to avoid such issue.

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.
