in iwlwifi: move setting up fw parameters

Meenakshi moved code up to configure the transport layer, but this
code read the sku before it was set (from the EEPROM). This killed
P2P.
Only the ucode_flags are needed to configure the transport layer, not
the sku which _must_ be set after the EEPROM is read.

We need to reconfigure the transport in case the EEPROM disabled PAN
support. This is not the nicest thing to do, but we have no choice.
Document that we are allowed to configure the transport several times
before start_fw, but not after.

The command queue number is required by the transport

Move this parameter to the dvm op mode, and configure

With the mac80211 deauth sequence changes, the
station is deleted before the device is set
unassociated. This can cause the device to get
confused as it expects the station to be there
while the associated bit is set.

To fix this, do not delete the AP station from
the device when mac80211 asks for deletion,
instead just mark it as unused and rely on the
unassociated RXON to drop it from the station
database in the device.

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 iwlwifi devices are most likely
not used on anything other than x86, this is not so important
