Conley Lee 47869e82c8 sun4i-emac.c: add dma support
Thanks for your review. Here is the new version for this patch.

This patch adds support for the emac rx dma present on sun4i. The emac
is able to move packets from rx fifo to RAM by using dma.

Change since v4.
  - rename sbk field to skb
  - rename alloc_emac_dma_req to emac_alloc_dma_req
  - using kzalloc(..., GPF_ATOMIC) in interrupt context to avoid
    sleeping
  - retry by using emac_inblk_32bit when emac_dma_inblk_32bit fails
  - fix some code style issues

Change since v5.
  - fix some code style issue

README

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.
