This is triggered by calling eth_schedule_poll(sw) after the IRQ has
been re-enabled.

Rework the network code to only enable IRQ's again if NAPI agrees it's
safe to do so.

Also only re-enable IRQ *after* cleaning up the RX ring and re-enabling
DMA, which otherwise resulted in ugly warnings regarding dirty page
fragments.
These popped up nearly immediately when building the kernel with O2 iso
Os.

--> Note that this change fixes stability issues, at the cost of ~8%
throughput performance.

While at it, also change the iface name being used in warning prints,
making it more obvious: "switch%d" --> "cns3xxx_eth"

The changes have been tested on 4 boards, each moving ~30TB of data

79366b8194 cns3xxx: fix GPIO controller interrupt enable
The cns3xxx interrupt controller uses a single register and as such
the 'mask' reg/functions must be used as opposed to the 'enable'/'disable'
reg/functions.

This fixes an issue that occurs if more than one GPIO on a specific controller
(there is GPIOA and GPIOB each having 32 GPIO's) uses interrupts. When one
would get enabled all others would be disabled prior to this patch.

84acff2865 cns3xxx: fix mpcore watchdog
The original implementation loaded the count register with (wrong) semi-
random values due to its implemenation nature.

If the wrongly calulated value was below the kickrate,
the WD was triggered and rebooted the system.

Rework this, partly based on upstream patches, to dynamically fetch the
current clockrate and calculate the proper offset for the WD countdown
register.

Before:

[  143.800000] count val: 27219720
[  148.820000] count val: 50623201
[  153.830000] count val: 96425250
[  158.830000] count val: 89735401
[  163.840000] count val: 4756110

After:

[    0.700000] MPCore WD init. clockrate: 299984500 prescaler: 256
countrate: 1171814 timeout: 60s
[  358.530000] count val: 35154751
[  363.540000] count val: 35154750

0b3a64f862 cns3xxx: eliminate hardcoded kernel/rootfs partition split
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.

f532191c1c cns3xxx: fix RX softIRQ loop
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.

687ab51fb2 cns3xxx: set both MPS 'and' MRSS to 128
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.
