brcmsmac: handle non PCI devices in the phy code

Some code in write_{radio,radio}_reg() should just be run if this is a
pci based device. Add the condition again which was removed in commit:

brcmsmac: remove PCIE() macro

Instead of checking if there is a PCIe core on the bus, better check if
hosttype is PCIe.

In the original submission to staging PCIE() checked, if the bustype is
PCI and the buscore is a PCIe core. Now we assume that all cores bcma
supports are PCIe based, so we just have to check if the bustype is PCI.

The old code bcmsmac currently uses searches for a PCIe core on the bus
and if there is one assumes that this is the buscore, which is wrong.
Some SoCs have a PCIe core operating in host mode and this is not the
bus core. The old code also caused a null pointer in
ai_get_buscoretype() and ai_get_buscorerev() if buscore was not set
because there was no PCIe core on the bus.

wlcore: change the wait for event mechanism

wlcore needs to wait for certain events for example
for roc complete event. Usually the events are received
from the FW very fast, therefore wlcore can poll with
a short delay and if after a second the event was
not received yet poll with a long (1-5 msec) delay.

This implementation is similar to the sending of
commands to the FW.

Empirically the change reduced the wait for roc event
from ~10-40msec to 100s of usecs.

wlcore: Prevent processing of work items during op_stop

The interrupt line is disabled in op_stop using disable_irq. Since
pending interrupts are synchronized, the mutex has to be released before
disabling the interrupt to avoid a deadlock with the interrupt handler.

In addition, the internal state of the driver is only set to 'off'
after the interrupt is disabled. Otherwise, if an interrupt fires after
the state is set but before the interrupt line is disabled, the
interrupt handler will not be able to acknowledge the interrupt
resulting in an interrupt storm.

The driver's operations might be called during recovery. If these
acquire the mutex after it was released by op_stop, but before the
driver's state is changed, they may queue new work items instead of just
failing. This is especially problematic in the case of scans, in which a
new scan may be scheduled after all scan requests were cancelled.
