====================
net: hisilicon: Add support for HI13X1 to hip04_eth

The main purpose of this patch series is to extend the
hip04_eth driver to support HI13X1_GMAC.

The offset and bitmap of some registers of HI13X1_GMAC
are different from hip04_eth common soc. In addition,
the definition of send descriptor and parsing descriptor
are different from hip04_eth common soc. So the macro
of the register offset is redefined to adapt the HI13X1_GMAC.

Clean up the sparse warning by the way.

Change since v1:
* Add a cover letter.
