The MFD_SYSCON depends on HAS_IOMEM so when selecting it avoid unmet
direct dependencies.

The HNS MDIO driver fails to build on older ARM machines that are not
yet converted to CONFIG_OF:
drivers/net/ethernet/hisilicon/hns_mdio.c: In function 'hns_mdio_bus_name':
drivers/net/ethernet/hisilicon/hns_mdio.c:405:14: error: 'OF_BAD_ADDR' undeclared (first use in this function)
u64 taddr = OF_BAD_ADDR;
^
drivers/net/ethernet/hisilicon/hns_mdio.c:405:14: note: each undeclared identifier is reported only once for each function it appears in
drivers/net/ethernet/hisilicon/hns_mdio.c:409:11: error: implicit declaration of function 'of_translate_address' [-Werror=implicit-function-declaration]
taddr = of_translate_address(np, addr);
^
This clarifies the dependency to ensure we don't attempt to build these
drivers without CONFIG_OF, but also adds a COMPILE_TEST alternative to
give us better build coverage testing.
Build-tested on x86 as well to ensure this actually works.

The newly introduced HNS_MDIO Kconfig symbol selects 'MDIO', but
that is the wrong symbol as the code used by this driver is
provided by PHYLIB rather than the MDIO driver. Also, there is
no need to make this driver user selectable, because it is already
selected by all drivers that need it.
This changes the Kconfig file to select the correct library, and
to make the option silent.

This is to add basic ethernet support for HNS. It is one of the way to
use the HNS acceleration engine. But most of the decoding/encoding
capability of the AE cannot be used in this way.
This submit contains the basic feature as a ethernet driver. More will
be added later.

DSAF, namely Distributed System Area Fabric, is one of the HNS
acceleration engine implementation. This patch add DSAF driver to the
system.
hns_ae_adapt: the adaptor for registering the driver to HNAE framework
hns_dsaf_mac: MAC cover interface for GE and XGE
hns_dsaf_gmac: GE (10/100/1000G Ethernet) MAC function
hns_dsaf_xgmac: XGE (10000+G Ethernet) MAC function
hns_dsaf_main: the platform device driver for the whole hardware
hns_dsaf_misc: some misc helper function, such as LED support
hns_dsaf_ppe: packet process engine function
hns_dsaf_rcb: ring buffer function

HNAE (Hisilicon Network Acceleration Engine) is a framework to provide a
unified ring buffer interface for Hisilicon Network Acceleration
Engines.
With the interface, upper layer can work as ethernet driver, ODP driver
or other service driver on purpose.

This howto made sense in the 1990s when users had to manually configure
ISA cards with jumpers or vendor utilities, but with the implementation
of PCI it became increasingly less and less relevant, to the point where
it has been well over a decade since I last updated it. And there is
no value in anyone else taking over updating it either.
However the references to it continue to spread as boiler plate text
from one Kconfig file into the next. We are not doing end users any
favours by pointing them at this old document, so lets kill it with
fire, once and for all, to hopefully stop any further spread.
No code is changed in this commit, just Kconfig help text.

Add support for the hix5hd2 XGMAC 1Gb ethernet device.
The controller requires two queues for tx and two queues for rx.
Controller fetch buffer from free queue and then push to used queue.
Diver should prepare free queue and free buffer from used queue.
