bcma_scan_bus allocates a bcma_core for each core found on the bus, but the
memory for cores handled by the bcma driver itself was not being freed when
the bus was unregistered. This patch adds special handling for the PCIE,
MIPS, and GBIT COMMON cores, to ensure that their memory allocation is
freed as well.
Note that this patch doesn't address the memory allocated for the CC core,
as that was corrected in my previous patch "bcma: register cc core driver,
device."

Tracing commands builds an array of trace data
items even when the tracepoint is disabled.
Instead, loop in the tracepoint assignment.
This reduces overhead if tracing is compiled
into the driver but not enabled and slightly
reduces overall driver size as well:

Since the firmware will give us an A-MPDU bit and
only a single PHY information packet for all the
subframes in an A-MPDU, we can easily report the
minimal A-MPDU information for radiotap.

The device only supports a maximum of three
antennas, and only three bits are used, the
fourth bit is the A-MPDU indicator.
The only consequence of this is reporting
invalid information in radiotap, so this
isn't an important change.

Because the hardware reports whenever an frame

The brcmsmac driver requests firmware but doesn't document the
dependency. This means that software that analyzes the modules to
determine if firmware is needed won't detect it.
Specifically, (at least) openSUSE won't install the kernel-firmware
package if no hardware requires it.
This patch adds the MODULE_FIRMWARE directives.

to provide sensible max output values for each

And while the eeprom always had a output_limit
table, which defines the upper limit for each
frequency and modulation, it was never really
useful for anything... until now.
