There are a few remaining drivers/staging/*/Makefile files that do not
have SPDX identifiers in them. Add the correct GPL-2.0 identifier to
them to make scanning tools happy.

If each phy port doesn't have its own resources, then we don't need

The ethernet in mt7621 is now supported by
drivers/net/ethernet/mediatek/
which provides support for the integrated switch through DSA.
This requires some devicetree changes, and particularly allows
a board dts to identify which switch ports are present.
The second CPU interface - gmac1 - doesn't work yet, so the device
tree information may not be correct. The phy (which is present on the
gnubee-pc2) can negotiate and report connection speed etc, but no
traffic flows.
The gnubee-pc1 has two network ports which are 'black' and 'blue'.
There are connected to switch ports 0 and 4 respectively.

The device-tree checking code sees node names "i2c" and "spi" in the
pinctrl definition and thinks these are defining i2c or spi devices,
and complains that they look wrong.
So add a '0' to the end of each name (much like "uart" and "rgmii"
have numbers at the end) to avoid the warning.

Since commit bb276262e88d ("mtd: spi-nor: only apply reset hacks to
broken hardware"), we need to mark the spi-nor as "broken" for reboot
to work.
Note that nothing is actually broken here. The hardware-watchdog in
the SoC isn't wired in a way that works, but then the board doesn't
claim to support a hardware watchdog - and the SPI certain isn't
"broken".
This causes an annoying warning on every boot, but that is better than
failing on ever reboot.

Banks shouldn't be defined in DT if number of resources
per bank is not variable. We actually know that this SoC
has three banks so take that into account in order to don't
overspecify the device tree. Device tree will only have one
node making it simple. Update device tree, binding doc and
code accordly.

The MT7621 documentation says that the sys clock - also known
as OCP clock for the Open Core Protocol - can be configured to
1/3 or 1/4 of the CPU clock.
Testing on my hardware, using the fact that the SPI clock is
based on the OCP clock and measuring transfer rates, shows
a clock of a little over 200MHz with a CPU clock of 900MHz.
So assume 1/4 is the default.
Also, the nor-flash in the gbpc1 is documented as accepting 50MHz
for request requests, and higher for other requests. So set
maximum to 50MHz.

Most gpio chips have two cells for interrupts and this should be also.
Set this property in the device tree accordly fixing this up. In order
to make this working properly the xlate function for the irq_domain must
be updated to use the 'irq_domain_xlate_twocell' one in the driver.
One more minimal change is needed two refer gpio's interrupt-parent from
other nodes which is to add new 'gpio' label in the device tree.

As the Interrupts for the PCI adapters are listed in
devicetree we shouldn't need to have them explicit in the code.
The simplest way to do this is to use of_irq_parse_and_map_pci()
and specify an interrupt-map which identifies the different
PCI hosts by bus/slot numbers.
This has the advantage that the hwirq number are mapped to virq
numbers for us, so the ugly hack can go.
