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.

HI13X1_GMAC changed the offsets and bitmaps for
GE_TX_LOCAL_PAGE_REG registers in the same peripheral
device on different models of the hip04_eth. With the
default configuration, HI13X1_GMAC can also work without
any writes to the GE_TX_LOCAL_PAGE_REG register.

otherwise, the subsequent initialization will not

In general, group is the same as the port, but some
boards specify a special group for better load
balancing of each processing unit.

In general, group is the same as the port, but some
boards specify a special group for better load
balancing of each processing unit.

The buf unit size of HI13X1_GMAC is cache_line_size,
which is 64, so the address we write to the buf register
needs to be shifted right by 6 bits.
The 31st bit of the PPE_CFG_CPU_ADD_ADDR register
of HI13X1_GMAC indicates whether to release the buffer
of the message, and the low indicates that it is valid.

HI13X1 changed the offsets and bitmaps for rx_desc
registers in the same peripheral device on different
models of the hip04_eth.

Thank you for your review, Great issue, which makes my code more concise.
I will fix it in v3. Or submit a patch to modify it separately, if maintainer
applies this patch series.

I decided to wait for this series of patches to sync to the mainline
and then fix this based on the mainline.
Because the mainline does not currently have this part of the code,
if I submit the changes, and the patch is accidentally merged into
another branch or another maintainer to handle, a conflict will occur.
As we all know, maintianer has to deal with many commits every day,
I don't want to increase the burden of maintainer.
So I decided to wait until the patch is synced to the mainline
and then modify it, which is more safe.
