Allocate memory from SoC internal SRAM to reduce DDR access and keep DDR in lower power state (such as self-referesh) longer. Check iram_pool before sdma_init() so that ccb/context could be allocated from iram because DDR maybe in self-referesh in lower power audio case while sdma still running.

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.
