New FW enables support for power save on BSS and P2P client MACs
simultaneously when they function on different channels (DCM).
Enable this case in the driver after examining new TLV flag -
IWL_UCODE_TLV_FLAGS_BSS_P2P_PS_DCM. Still power management is not
allowed on both MACs if they function on a same channel.
Remove another redundant TLV flag - IWL_UCODE_TLV_FLAGS_P2P_PS that

e.g.
echo '0xA01234 0x99' > /sys/kernel/debug/ieee80211/phy0/iwlwifi/iwlmvm/prph_reg
will write 0x99 into reg 0xA01234
cat /sys/kernel/debug/ieee80211/phy0/iwlwifi/iwlmvm/prph_reg

If LTK distribution happens in both directions we will have two LTKs for
the same remote device: one which is used when we're connecting as
master and another when we're connecting as slave. When looking up LTKs
from the locally stored list we shouldn't blindly return the first match
but also consider which type of key is in question. If we do not do this
we may end up selecting an incorrect encryption key for a connection.
This patch fixes the issue by always specifying to the LTK lookup
functions whether we're looking for a master or a slave key.

So far we've only been requesting the LTK to be distributed to the
master (initiator) of pairing, which is usually enough since it's the
master that will establish future connections and initiate encryption.
However, in the case that both devices support switching to the opposing
role (which seems to be increasingly common) pairing will have to
performed again since the "new" master will not have all information.
As there is no real harm in it, this patch updates the code to always
try distributing the LTK also to the slave device, thereby enabling role
switches for future connections.
