In the original submission to staging PCIE() checked, if the bustype is

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

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.

wlcore: enable sched scan while connected
New wl12xx firmware supports scheduled scans also while connected.
Stop blocking sched scan requests when connected and add a quirk to
block in hardware that don't support it (currently wl18xx doesn't).
This requires FW version 6/7.3.10.2.112 for single-role and
6/7.5.6.0.25 for multi-role.
