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.

Disable ARCH_NEEDS_CPU_IDLE_COUPLED by-default in generic config, since
only one platfrom (omap) needs them.

CONFIG_GENERIC_NET_UTILS is selected by CONFIG_NET and already enabled
in generic config, so we don't need this symbol in platform specific
configurations.

modules build during the kernel compile phase are ignored anyway,
all modules should be built using KernelPackage in
package/kernel/linux/modules/*
selecting the appropriate config symbols there rather than in
target/linux/*/config-*

replace all occurences of LINUX_VERSION with the cleaner
approach. future kernel upgrades must mostly touch only
one file. the only platform left is netlogic, because it
uses a intermediate kernel 3.14.16

Have gpio driver adopt irqdomain support so that there are
non-overlapping allocations of irq numbers mapped to gpio's.

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.
