Use vmalloc to allocate memory for the firmware image, and use a smaller
linear buffer for the actual transfer of the firmware to the chipset.
This patch is an adaptation of a similar patch for wl1251 by Kalle Valo.

Enable multicast filtering. This way by default no multicast frames will
reach the host, and when needed, only required multicast frames can be
passed from the WLAN chipset to the host.

Implement delayed entry into ELP. This will promote the following:
- Less redundant sleep/wake cycles (better perf)
- Avoids known firmware issues with going to ELP too fast after an

Over time, a whole bunch of drivers have come up
with their own scheme to delay the configure_filter
operation to a workqueue. To be able to simplify
things, allow configure_filter to sleep, and add
a new prepare_multicast callback that drivers that
need the multicast address list implement. This new
callback must be atomic, but most drivers either
don't care or just calculate a hash which can be
done atomically and then uploaded to the hardware
non-atomically.
A cursory look suggests that at76c50x-usb, ar9170,
mwl8k (which is actually very broken now), rt2x00,
wl1251, wl1271 and zd1211 should make use of this
new capability.

This driver supports the wl1271 chipset from Texas Instruments based on the
WiLink(tm) 6.0 mobile platform. Support for wl1273 should be relatively easy
to add. This chipset is designed for embedded devices, with good powersaving
capabilities. The wl1271 chipset is the successor of wl1251 and supports the
802.11b/g/n standards, but currently this driver supports only b/g.
More information about this chipset can be found here:
