FW now supports dynamic PS so we don't need to use mac80211 support.
FW will go to PSM after a specified timeout with no Rx/Tx traffic.
- Changed FW API to include new PS mode (AUTO_MODE) and including timeout parameter
- The default PS mode would be dynamic PS
- Default timeout is 100ms (same as it used to be in mac80211)
- Avoid using mac80211 APIs to disable/enable dynamic PS as we're not
using mac80211 PS control anymore.
- COEX is handled by the FW while in dynamic PS so removed
handling of SOFT_GEMINI

Add a testmode command to retrieve the BD_ADDR that is stored in the

Signed-off-by: NLuciano Coelho <coelho@ti.com>

Add support for two MAC addresses.  If the NVS has a valid MAC
address, that takes precedence and we use two sequential address
starting from the one specified.

If the NVS doesn't contain a valid MAC address (ie. if it is set to
00:00:00:00:00:00), we check if the HW PG version in use has the
BD_ADDR written in the fuse ROM.  If it does, we read it and derive
the two subsequent addresses for WLAN.

During production, 3 addresses are reserved per device.  The first for
Bluetooth (burnt in the fuse ROM) and the following two for WLAN.

This patch has some code by Igal and Arik (squashed from internal
patches).

In order to read the MAC addresses from the fuse ROM, we need to know
the chip ID and the HW PG version.  We need to know the MAC address
during probe, because that's when we register our HW with mac80211.

To prepare for that, this patch reads the chip ID and HW PG version
during probe instead of doing it at boot time.  We power the chip on
briefly in order to do that.
Signed-off-by: NLuciano Coelho <coelho@ti.com>

Up till now we only needed to access the partition table in boot.c.
But to add support for reading the MAC address from the FUSE in
testmode, we will have to change the partition in testmode.c.

Thus, we move the partition table to io.c and export it via io.h.  It
makes more sense to have it in the io part anyway.
