c44506fcbd cns3xxx: fix an rx irq handling corner case 
When an rx interrupt comes in, rx interrupts are disabled and NAPI
polling is scheduled. During the NAPI poll, the driver first processes
received frames in the ring, then fills the dma descriptor slots with
new buffers and calls tx complete, before finally re-enabling rx
interrupts and completing NAPI (if below the budget).
If the hardware rx queue overflows before the napi complete is called,
the hardware will not throw any further rx interrupts and rx processing
stops completely.
Fix this by keeping NAPI polling scheduled until it completes a poll
without receiving any packets, and also handle NAPI completion before
refilling rx or completing tx.

3c12bad276 move PCIe init to subsys init call 
ARM Linux PCI/PCIe hardware intialization needs to occur before device_init
as it does not support hotplug.  I have modeled the cns3xxx PCIe init after
other ARM platforms.  Registering it early resolves resource issues occuring
during bus enumeration that occur when a device driver is linked static in
the kernel.

Instead of passing in a bitmask to enable the 2 available ports, link detect
is used to enable ports that have a valid link.

Note that the FIQ support implements a workaround that provides a performance

6bb7409e5a cns3xxx: Fix laguna arm11mpcore watchdog 
The ARM11MPCore Timer/Watchdog registers start at offset 0x600 which is where
all mpcore-wdt boards point the driver base too.  I believe this is wrong
because 0x600 is aliased to the timer/watchdog of the 'current CPU' where
0x700 is CPU0's timer/watchdog, and 0x800 is CPU1's timer/watchdog.  Thus
if your timer/watchdog application is switching between CPU's it can end up
writing to the wrong CPU's registers which results in random board resets
from watchdog timeouts etc.

This patch forces the timer/watchdog driver to use CPU0's registers always.
Its my opinion that other mpcore-wdt boards should be doing the same thing.
