a5f16137ab iwlegacy: use writeb,writel,readl directly
That change will save us some CPU cycles at run time. Having
port-based I/O seems to be not possible for PCIe devices.

4e5ea2088b iwlegacy: cleanup/fix memory barriers
wmb(), rmb() are not needed when writel(), readl() are used as
accessors for MMIO. We use them indirectly via iowrite32(),
ioread32().

What is needed mmiowb(), for synchronizing writes coming from
different CPUs on PCIe bridge (see in patch comments). This
fortunately is not needed on x86, where mmiowb() is just
defined as compiler barrier. As iwlegacy devices are most likely
not used on anything other than x86, this is not so important
fix.

Before we write to the device register always check if
_il_grap_nic_access() was successful.

Change type return type _il_grap_nic_access() to bool, and
add likely()/unlikely() statements.

b6603036ad iwlegacy: dump stack when fail to gain access to the device
Print dump stack when the device is not responding. This should give
some more clue about the reason of failure. Also change the message we
print, since "MAC in deep sleep" is kinda confusing.

On the way add unlikely(), as fail to gain NIC access is hmm ...
unlikely.

We have disable ability to change passive scanning to active on
particular channel when traffic is detected on that channel. Otherwise
firmware will report error, when we try to do passive scan on radar
channels.
