Add support to enable beacon early termination in the firmware. Early
Beacon termination is a feature which allows the radio to be turned off
after TIM IE to save power.

In order to make the firmware configuration more manageable, collect

there.
Add the SoftGemini BT/WLAN coex paramters into the config structure.

We were using the join command to change some settings when the stack asked
us to do it. In many cases they were not needed (and could cause potential
problems), so they were removed. In other cases there are ACX commands that
can be used instead of using join to reconfigure.

With the change to the new firmware, there was a change to firmware memory
partitioning. Along with that change, the translation of all partitions was
unified, and separate functions for reg and mem access became unnecessary.
Cleanup the unnecessary functions.

We don't get any indication from the stack when we have disassociated. In
wl1271, it is important to send a CMD_DISCONNECT before joining again,
because the firmware cleans some things up. So we check if we're already
joined and disconnect if that's the case.
