commit 328c32f0f85467af5a6c4c3289e168d9ad2555af upstream.
Currently SDIO glue frees it's own structure before calling
wl1251_free_hw(), which in turn calls ieee80211_unregister_hw().
The later call may result in a need to communicate with the chip
to stop it (as it happens now if the interface is still up before
rmmod), which means calls are made back to the glue, resulting in
freed memory access.
Fix this by freeing glue data last.

wl12xx_get_platform_data() returns an ERR_PTR on failure and it never
returns a NULL.

Make use the newly added method to pass platform data for wl1251 too.
This allows to eliminate some redundant code.

Add runtime PM support, similar to how it's done for wl1271.
This allows to power down the card when the driver is loaded but
network is not in use.

Call interface specific power callback before calling board specific
one. Also allow that callback to fail. This is how it's done for
wl1271 and will be used for runtime_pm support.

wl1271 driver is under heavy development but on the other hand the older
wl1251 driver is currently considered more as a legacy driver. To make it
easier to develop wl1271 features move wl1251 to it's own directory,
drivers/net/wireless/wl1251.
There are no functional changes, only moving of files. One regression
is that Kconfig won't be updated automatically and user needs to enable
wl1251 manually with an older config file.
