Refresh patches for all targets that support kernel 4.4.
Compile-tested on all targets that use kernel 4.4 and aren't marked
broken, except arc770 and arch38 due to broken toolchain.
Runtime-tested on ar71xx, octeon, ramips and x86/64.

Port 1 registers the same IO resources as port 2 in the kernel resource
tree, which is wrong.
Fix this by using it's own resources as indicated in the overview
(cns3xxx.h).
Compiled & Tested on several GW2388-4 laguna boards which utilizes all 3
ports.

This changes the sysupgrade format. To support upgrades from the old
firmware to the new one, legacy images are provided. Because of the old
partition split, these have to be specific to the NOR or SPI device.
The new sysupgrade images are suitable for begin put on flash directly,
and they are independent of NOR vs SPI flash variant.
Flashing back to old firmware is supported via using the old full-flash
images instead of the old sysupgrade images.

Already reschedule when 1 or more frames came in.
Checking for a full queue could produce a re-schedule loop as
the checked RX ring location could contain undefined values
depending on activity in previous loops.

Fixes some DMA issues with this platform. Because this isn't currently accepted,
and can potentially disrupt other platforms (as read in commit log), I will
leave this cns3xxx specific.

This patch originally failed to combine INTA/B/C/D onto a single ARM CPU
interrupt. Instead, it mapped INTA/B/C and excluded D. This patch
corrects the issue by mapping all four interrupts to the single ARM CPU
interrupt. The original intent of the patch still holds as the newer PCB
take advantage of isolated interrupts. This fix only applies to older
PCB's that do not route INTA/B/C/D to unique external ARM CPU
interrupts.

The cns3xxx uses irq61 for pcie0_intr which in the case of a PCIe-to-PCI
bridge ends up combining INTA/B/C/D on a single ARM CPU interrupt. This is
not optimal when you have multiple cores. To overcome this limitation an
enhancement was made on newer Laguna PCB's that support miniPCI cards
to route the INTA/B/C/D signals to unique external ARM CPU interrupts which
can help balance CPU core utilization and in some cases increase overall
system performance or responsiveness.

but we should at least correct it. the error was observable like this:

This reverts commit 0772ab938c0aedd7f4cc7127059d6ce8cf929dfa.
Trying to optimize calls to eth_complete_tx in this fasion causes a regression
where when sending only the tx queue can get disabled until a packet is
received. This original call to eth_schedule_poll() is scheduled so it
should not cause a performance issue.

We already clean up tx descriptors in the napi eth_poll() function so it
would likely be rare to run out of available descriptors in eth_xmit. Thus
we can clean them up only when needed and return busy only when we
still don't have enough.

The combination of r35942 and r35952 causes an issue where eth_schedule_poll()
can be called from a different CPU between the call to napi_complete() and the
setting of cur_index which can break the rx ring accounting and cause ethernet
latency and/or ethernet stalls. The issue can be easilly created by adding
a couple of artificial delays such as:

This patch moves the setting of cur_index back up where it needs to be and
addresses the original corner case that r35942 was trying to catch in an
improved fashion by checking to see if the rx descriptor ring has become
full before interrupts were re-enabled so that a poll can be scheduled again
and avoid an rx stall caused by rx interrupts ceasing to fire again.
